Went to a flea market and found a trumpet that I assume to be from the WWII era and probably in E-flat. Y'all have some guesses to what this could be?

This was sitting in a pawn shop for a year or so and they put it on clearance. Got it for a great deal.

Well, didn't expect this, but won this at auction today. I'll put up more pics once I get it, the auction was lacking, so it's a bit of a gamble. So far I've determined it's pre 1957 due to the type pinky ring. While the earlier 1950s models with the "pineapple" stamp get a lot of collector attention, those Monopoles made after the disappearance of the stamp in the mid 50's are often considered more "modern" players. I've narrowed his one down to pre 1957 bc that's when the pinky ring was changed to the C looking one and this has a standard pinky ring. And the pineapple date tear stamp disappeared in the early 50's. So this is likely 54-67

• The Leadpipe: Couesnon refined their leadpipe tapers in this era. They tend to be slightly less "stuffy" than the very early post-war models, offering better slotting for modern playing.
• Silver Plate Durability: Couesnon's silver plating from this period was exceptionally high quality. Unlike their lacquer, which was notoriously thin, the silver plate on these horns often stays in excellent condition for decades, protecting the yellow brass from the "red rot" often found on vintage student horns.
• Intonation: By the late 60s, Couesnon had improved the consistency of their valve blocks. These horns generally have better intonation across the partials compared to the 1940s versions, which sometimes required more "lipping" of certain notes.

Besson’s use of Couesnon valve blocks was a direct result of the financial collapse and physical destruction of the original French Besson factory.

The timeline for the integration of Couesnon parts into Besson instruments follows these key milestones:

1. The Pre-War "Neighbors" Era (1930s)

Before the factories officially merged, Couesnon and F. Besson were located "next door" to each other in Paris. During this era, Couesnon produced many instruments that were visually near-identical to Besson models. While they weren't officially sharing valve blocks yet, the cross-pollination of French design was already well-established.

2. The Post-War Crisis (1948–1957)

In 1948, a major fire destroyed the F. Besson factory in Paris. This effectively ended the era of the legendary "Pre-War French Besson" produced by original Besson craftsmen. For nearly a decade, the brand was in a state of limbo.

While 1957 was the year Couesnon officially swallowed the Fontaine-Besson name, they had already moved in together by 1951.

The "Editions Hawkes" Partnership (1951)

In 1951, F. Besson was nearly bankrupt following the 1948 factory fire. A deal was struck where Geoffrey Hawkes (of Boosey & Hawkes) and Couesnon SA formed a joint venture called Editions Hawkes.

• The Split: Hawkes owned 60%, and Couesnon owned 40%.
• The Production: From this point on, Couesnon began supplying the parts and valve blocks that were assembled into "French Besson" trumpets at the Rue du Faubourg location.

3. The Couesnon Acquisition (1957)

Following the death of Mathilde Besson (the daughter of Gustave-Auguste Besson) in 1957, Couesnon purchased the F. Besson name and assets.

• Valve Production: From 1957 onward, "Post-War" French Besson trumpets and cornets were manufactured and assembled using parts from the Couesnon factories.
• Valve Design: These instruments featured Couesnon's valve blocks, which, while high-quality, differed from the unique "Besson-feel" of the 1920s.

4. The Unified Era (1960s)

By the early 1960s, the production was fully integrated. If you find an F. Besson trumpet from this era, it is essentially a high-end variant built by Couesnon. This continued until the 1969 Couesnon fire, which again halted production and forced the brand to shift its manufacturing base.

How to Tell if You Have a Couesnon-Made Besson

If you are looking at a Besson and suspect it has a Couesnon valve block, look for these markers:

• The "Star" or "Monopole" Style: The valve casings often mirror the style of the Couesnon Monopole series.
• Valve Caps: Look for the knurling patterns on the valve caps; Couesnon-made blocks typically used the same caps across their various brands.

This shared history is why the 1960s Couesnon Monopole Conservatoire (SN 18976) is so highly regarded; it shares the same lineage and manufacturing DNA as the pro-level French Bessons of that same decade.

Component	Detail
Model	Monopole Conservatoire (Top-tier Professional)
Era	Mid-to-Late 1950s (Pre-1969 fire)

The 1932 is basically a special order Conn 2B New World Symphony without the 1st & 3rd stop rods or 1st slide saddle, and with a pinky ring rather than a hook on the leadpipe, which is interesting since 1932 was the last year for the 2B, so maybe the US Army(USQMC, U.S. Quartermaster Corps) got a deal on them.

The 1940 is considered the height of the 22B builds as they got lighter later, likely due to material shortages and lighter bells & dropping the MTS stop rod after 1946, to

• 1942 - 2 Lbs. 7.3 oz.
• 1948 - 2 Lbs. 6.5 oz.
• 1953 - 2 Lbs. 5.5 oz.

Both play wonderfully with a tone comparable to a Bach 37, with perfect intonation and slotting.

I got lucky and both have excellent valve compression giving a nice pop when slides removed.

Was just playing this today using my original Jet-tone Severinsen mouthpiece which is a

Throat	Cup OD	Cup OD (INCHES)	Rim Width (mm)	Rim Width (inches)	Cup ID (mm)	Cup ID (INCHES)	Cup Depth (mm)	Cup Depth (INCHES)
22	26.60	1.05	5.00	0.20	16.60	0.65	11.80	0.46

Such a great playing and sounding horn with lightning valves. And being a 1st year with factory trigger in pristine condition WITH the extra factory 0.458" slide in original envelope. One my favorites in my collection.

Traits: Brilliant, cutting tone; free-blowing; designed for jazz/lead; trigger aids intonation. The 0.460" bore and silver plating produce a lively, sparkling sound, perfect for big band and commercial but less warm for classical.

Specs: .460" bore, 1st valve trigger, extra .458" tuning slide, original case, Jet-tone Severinsen mouthpiece

Pros:
1st valve trigger boosts playability and value—worth $100-$200 over non-triggered models.

Extra .458" slide, though standard on early Severinsens, is a significant asset given its rarity today.

.460" bore is versatile and widely appealing.

1964 vintage status and very good condition are strong.

Cons:
.458" vs. .460" bore difference remains subtle, so the slide’s value is more about possession than dramatic playability shifts.

Overview:
Model: The Getzen Eterna Severinsen is a professional-grade trumpet developed in collaboration with Doc Severinsen, famed Tonight Show bandleader and trumpet virtuoso. Introduced in the mid-1960s, it was designed to meet Doc’s demands for versatility, brilliance, and playability across jazz, studio, and big band settings.

Serial Number: SK1077, it dates to 1964-1965 This places it early in the Severinsen line, shortly after its debut.

Specifications:
.460" Bore: A medium-large bore, striking a balance between resistance and projection. It’s smaller than true large-bore horns (.468"-.470"), making it less taxing on air while still delivering a full, bright tone—ideal for jazz soloists or lead players who want control without sacrificing power. Compared to modern standards (e.g., Bach’s .459"), it’s slightly bigger, aligning with Getzen’s pro focus.

Factory 1st Slide Trigger: A premium feature, rare on mid-’60s trumpets outside top-tier models. It allows quick intonation adjustments (especially on 1st valve notes like D and C#), a boon for pros needing pitch precision in live or studio work. Getzen integrated this seamlessly, reflecting Doc’s input for technical playability.

Factory Extra .458" Tuning Slide: Included as standard on early Severinsens, this slide is a hair smaller than the .460" bore (.002" difference). It subtly tightens resistance and might brighten the tone slightly—more a fine-tuning option than a drastic shift. Its rarity today boosts value, as many are lost after 50+ years.

Jet-Tone Severinsen mouthpiece:

Sound: Brilliant, cutting; shallow cup maximizes Getzen’s lead potential with sparkling highs.

Original Case: hard case from Getzen’s ’60s lineup—durable, wood-framed with vinyl or leatherette covering. Adds authenticity and practical protection. Very heavy duty.

Historical Context:
1964-1965 Production: SK1077 slots into Getzen’s post-1963 reboot after a devastating fire. The Elkhorn, WI factory was hitting its stride, and the Severinsen line was a flagship, launched around 1964-1965 with Doc’s endorsement. This horn’s an early example—built when Getzen was refining the design with pro feedback.

Doc Severinsen’s Influence: Doc wanted a horn that could “sing” in any setting—bright for lead, warm for ballads. The .460" bore and trigger reflect this, offering flexibility over raw power (unlike later large-bore variants). The extra slide nods to customization, a hallmark of his hands-on approach.

Construction & Materials:
Leadpipe: Silver plated brass

Build: Hand-assembled with Getzen’s signature tight tolerances—smooth valves, solid bracing. The trigger mechanism would be factory-installed, not retrofitted, ensuring balance and reliability.

Playability:
Responsive horn with a focused, brilliant tone—Doc’s signature sound. The .460" bore keeps it nimble, while the trigger aids intonation, making it versatile for jazz, classical, or lead. The .458" slide might lighten the feel slightly, letting you tweak for comfort or room acoustics.

Collectibility: SK1077’s early date (1965-1966) adds vintage cred—pre-dating Doc’s ’70s peak fame but tied to the model’s origin story. The full kit (case, slide) enhances its appeal.

Fun Fact:
Doc played Getzen Severinsens on The Tonight Show, often customizing them. Your SK1077 might not be his horn, but it’s from the same lineage—built when he was shaping the design. I actually heard that he had one with a Bach Strad 72 bell on it.

I bought this weighted cap kit made for a Conn 52B Connstellation thinking I might be able to use it. Turns out it fits my Bach Strads just fine. Also fits my Benge 1960 2C+ MLP C trumpet and my King 1965 Silver Flair 1055T which might need more slotting help being a C.. I've never tried weights, but will be interesting to experiment. I've been considering buy a 51B, so should work on that too.

Any suggestions appreciated

I posted this earlier here https://www.reddit.com/r/Vintage_Trumpets/comments/1rpfdbw/olds_1947_super_cornet_no_case_los_angeles_18540/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button before I cleaned it up. I've found that, considering the Olds large shank mouthpiece dilemma (Prior to serial number 189,611, Olds cornets had a larger receiver than other standard cornets, info here https://olds-central.com/olds-large-shank-cornet-mouthpieces/ ), the early Rudy Muck mouthpieces work great on them. Had someone asking earlier about choosing between a 1948 Super and a 1960 one, which should he get, the earlier ones sound so great, and project better than almost any cornet I've played. According to Clay Colins "Robb Stewart has analyzed the differences in detail, and his theory is that the difference between the two has a lot more to do with the player than anything else! He has an interesting essay on his website ( https://www.robbstewart.com/difference-between-trumpet-and-cornet ) that provides much more detail . While still a cornet, the Super Cornet is much more trumpet sounding than other cornets of this era. Perhaps Olds was trying to bridge the gap and offer a cornet to those that still were still in the cornet camp, but with modern styling and the ability to blend more easily with trumpets. "

This one is very well used, has a replacement front bell to receiver brace, engraving on the bell barely visible, but man does it play, and such a nice dark sound, more trumpet like than cornet. Didn't cost much, about $140, but I really love this horn.

CG Conn 4B New Wonder Symphony (Serial Number 172165) is a fascinating piece because it represents the "Big Brother" to the later more common 22B New York Symphony and 2B New World Symphony that era.

Production & Identification

Made from 1919-1925, then 1926-33 as the New World Symphony. According to Conn’s factory records, serial number 172165 was manufactured in 1920. At this time, the "New Wonder" series was Conn's top-tier professional line, just before they transitioned models to the "New World Symphony" branding in 1926.

Technical Specifications

The 4B was specifically designed for players who found it provided a broader, more "symphonic" sound.

Feature	Specification
Model	4B New Wonder Symphony
Bore Size	#1 ½ Bore (.459")
Bell Diameter	4 5/8"
Material	One-piece "French Brass" bell
Valves	Top-spring, bottom-vented pistons
Key	Bb with A-change capability

• The "Blow": The .459" bore of the 4B is what most modern players consider "Medium-Large." The 4B is much more open and "free-blowing," requiring more air support but offering a much larger volume of sound.
• The Leadpipe: The 4B typically has a slightly more "conical" taper in the leadpipe to balance the larger bore, helping it maintain the characteristic "Conn shimmer" without becoming overly dark.
• The "New Wonder" Look: In 1920, these often featured very intricate "Art Deco" or floral engravings.

Historical Context

The 4B Symphony is somewhat rare. While the later 22B became the "standard" for its laser-like precision, the 4B was the choice for the principal players in major orchestras (like the Philadelphia or Chicago) who needed to fill a massive hall. It is essentially the ancestor to the modern "large bore" symphonic trumpet.

The Effect of the Narrower Bell

Since the 4B pairs a larger #1 ½ Bore (.459") with that smaller 4 5/8" bell, it creates a unique playing characteristic:

• Focus: The smaller flare helps "compress" the sound from the larger bore, giving it more "zip" and "cut" than a modern horn with similar bore specs.
• Projection: These vintage Conns were famous for being "lasers" in the orchestra—they don't necessarily sound the loudest to the player, but the sound carries to the back of the hall with incredible clarity.
• 1920 4B Symphony actually has a narrower, more compact bell flare compared to modern standards. This was a hallmark of that era's "true trumpet" sound—prioritizing a tight, directional core over the massive, spread-out "wall of sound" favored by modern large-bell designs.

I bought this horn from a seller in British Columbia, Canada a couple years ago and have been attempting to research it's provenance. I may be close to finding some of it. It had a note with it on some of it's previous ownership, detailing it as having belonged to a Joe Royals who played with the big bands like Tommy Dorcey and such, who was given it by his father who also played with the big bands. It also mentions being owned/played by a Manuel in Hawaii on one of his nightly performances at the King Kam (assume the The King Kamehameha Hotel (King Kam) in Kona which was a major hub for professional entertainment in Hawaii from the 1970s onwards.), where he joked it was an antique.(fitting it being 1970s onward).

The note reads:

"Joe Royals was a Shriner originally from the U.S.A. who played the trumpet & euphonium in some of the big bands such as Tommy Dorsey etc. The trumpet belonged to his father who also played in the big bands.

I believe the trumpet is a model produced in 1936 by Conn Limited Elkhart Indiana U.S.A.

Manuel in Hawaii played this trumpet on one of his nightly performances at the King Kam Hotel & used to kid that it was an antique

Serial # 281880 PATENTED"

I've located a Joseph Royal as follows in Vancouver/Victoria BC, Canada:

The Professional "Paper Trail"

• BC Musicians' Association (Local 247): Joseph Royal (singular) was a long-standing member of the Victoria/Vancouver Musicians' Union. In the 1970s and 80s, he was specifically listed as a Trumpet/Cornet soloist for hire. He was a regular in the "Pit Bands" and hotel orchestras that supported touring acts in Victoria.
• The RCAF Musician Branch: His WWII service in the Royal Canadian Air Force (RCAF) was not in a combat role, but as a Musician. The RCAF had elite bands (like the Streamliners) that were the Canadian equivalent of the Glenn Miller AAF Band. Every man in those bands had to be a top-tier professional; he wasn't just a soldier who played—he was a professional musician who was drafted.
• The Gizeh Shrine Band: In British Columbia, the Gizeh Shriners (where he was active) had a very high-caliber brass band. Local performance reviews in the Victoria Times-Colonist and Nanaimo Daily News from the mid-80s occasionally mention the "brass section" or "featured soloists" of the Shrine band during parades and benefit concerts.

That's all I have so far, but as much as it fits, it seems out of order, unless Joe Royal bought it later in life from someone in Hawaii, which would fit the timeline better. But then that leaves it's pre 70's history still a question. I guess it makes sense that a veteran trumpet player, like myself, would be more apt to buy a former military engraved horn.

It has "quirks" I've identified that are key to this horn's identity. They show it's not a standard catalog 22B—but a Military Contract Special.

When the U.S.Q.M.C. (Quartermaster Corps) put out a bid for instruments in the early 30s, they weren't looking for the latest "clickless" commercial fads. They wanted durability, parts commonality, and specific ergonomic layouts detailed in 1932 Quartermaster Corps Specification No. 11-13A for "Trumpets, Bb,". Since the 2B was discontinued in 1932, this likely was some of the reason for the 2B parts such as the 1st valve side setup and the top sprung adjustable spring tension valves.

Technical Breakdown of the "Quirks"

Feature	Your USQMC Horn	Standard 1932 22B	Why the Difference?
Valve Springs	Top Sprung	Bottom Sprung	By 1932, Conn was pushing "Clickless" bottom springs. The military often specified top springs because they were easier to field-service and harder to "lose" during a cleaning in a barracks setting.
1st Valve Slide	Reversed	Standard / Optional	The reversed 1st slide (top tube outside) is a classic Conn 2B Symphony trait. Your horn seems to be a "Hybrid" using the 2B's more robust slide architecture on a 22B-sized frame.
Finger Grip	Pinky Ring	Finger Hook	Most commercial 22Bs had the hook by 1930. The ring was standard on the older 2B and early 22Bs. The military likely preferred the ring for a more "locked-in" grip during mounted maneuvers or marching.

The "2B vs. 22B" Mystery

In 1932, Conn was phasing out the 2B Symphony (Medium bore) and making the 22B New York Symphony (Small bore) their flagship. Your horn, with its serial #281880, sits right at that transition point.

The fact that it has top-sprung valves and a reversed 1st slide suggests the Army might have actually ordered a batch of 2Bs or a "Military Specification" 22B built with 2B components. The Quartermaster Corps valued "ruggedized" designs, and the older 2B valve block was legendary for its reliability.

The Player: Joseph Royal (1920–1994)

The possible horn owner was a professional:

• RCAF Musician: Joseph Royal (singular) is documented as an RCAF veteran (WWII). He wasn't a clerk; he was a Musician. Getting into a Canadian military band in the 40s required professional-level sight-reading and tone.
• The BC Legacy: He died in Victoria, BC, on December 21, 1994. The fact that he lived in the same region where I found the horn, and was a known member of the Victoria Musicians' Union, is the possible link.

Summary: a "Military Special" hybrid—built like a 2B but sized like a 22B—owned by a professional RCAF bandsman. It is likely a most unique instrument from that 1932 contract.

***Update***

Based on the note and the timeline we've established, there are two high-probability "Manuels" in the Hawaii music scene who fit the "Manuel in Hawaii" description.

The note mentions Manuel played "nightly at the King Kam Hotel." While the King Kamehameha Hotel in Kona is famous today, in the big band era of the 40s and 50s, many hotel musicians in Honolulu also played the "King Kamehameha" rooms or associated lounges.

Top Candidates for "Manuel"

Candidate	Background	Relevance
Manuel Silva	A well-known musician and member of the Royal Hawaiian Band.	Silva was a prominent figure in the Hawaiian musical community. Historical records from the Hawaiian Journal of History mention him specifically as a legacy member.
Manuel "Manny" Rezentes	A veteran musician in the Honolulu scene during the mid-20th century.	Many musicians in the hotel circuit (like the King Kam or the Royal Hawaiian Hotel) were of Portuguese or Filipino descent and went by "Manuel" or "Manny."

A Theory on the Provenance

Since your horn is a 1932 USQMC (U.S. Quartermaster Corps) model, it was government property. Hawaii was a massive military hub during WWII. It is highly likely the horn was:

1. Issued to a military band in Hawaii during the 1930s or 40s.
2. Decommissioned or sold as surplus in Hawaii after the war (or simply "kept" by a departing musician).
3. Acquired by "Manuel," who used it for his nightly hotel gigs. By the 1950s or 60s, a 1932 Conn would definitely be considered an "antique" by a working pro.
4. Sold to Joe Royal's father, likely another big-band musician traveling through or working in the Pacific circuit, who then brought it back to Canada.

The "Shriner" Connection

The note mentions Joe Royal was a Shriner. The Shriners have a very strong tradition of brass bands (Oriental Bands). If Manuel was also a Shriner—or if Joe's father met Manuel through a Shriner connection in Hawaii—it would explain how a specific instrument traveled from a hotel gig in Hawaii to a collection in British Columbia.

Period	Owner / Location	Status of the Horn
1932	USQMC (U.S. Army)	Brand new government issue; likely stationed at Fort DeRussy or Schofield Barracks, Hawaii.
~1950s-60s	Manuel (Hawaii)	Nightly performer at the King Kam Hotel. This is when the "antique" jokes likely happened.
~1970s	Joe Royal's Father	Likely purchased from Manuel or an estate and brought to Canada.
Until 1994	Joe Royal (BC, Canada)	Played and kept by Joe, a fellow Big Band and Shriner musician.

Based on the details in that note and the 1932 serial number, here are the likely candidates for the Manuel who owned your Conn 22B:

Name	Role / Context	Why he fits
Manuel "Manny" Rezentes	A mainstay in the Honolulu and Waikiki hotel circuits during the 50s and 60s.	Many "hotel" musicians in Hawaii were of Portuguese descent and worked the nightly lounge circuits like the King Kam.
Manuel Enos Silva (Jr.)	The Silva name was synonymous with brass in Hawaii. A younger relative of the original Manuel Silva.	Professional musicians often kept "antique" horns (like a 1932 Conn) as backup or for specific "small-bore" jazz sounds.
Manuel [Surname Unknown]	A member of the Royal Hawaiian Band or Aloha Shrine Band.	Since Joe Royal was a Shriner, it is highly probable the "Manuel" in the note was a fellow Shriner musician.
Manuel Ferreira	U.S. Army Veteran. Served in the Hawaii Department (likely where the USQMC horn originated).	1892–1983. Born earlier, but definitely active in the music scene.

Candidate 1: Manuel "Manny" Silva Jr.

This is the strongest match for a "legacy" musician. In Hawaii, the Silva family was effectively the "First Family" of brass, with multiple generations playing in the Royal Hawaiian Band and hotel orchestras.

• Birth/Death: October 15, 1910 – October 15, 2001 (approximately).
• Why he fits: He was part of the generation that bridge the gap between the pre-war military bands and the post-war hotel era. He was active in the 1960s when your note says "Manuel" played nightly at the King Kam.
• The "Antique" Joke: Being born in 1910, he was a contemporary of the 1932 Conn. By the late 60s, he would have been an "elder statesman" of the hotel scene, making the joke about his 30-year-old horn being an "antique" perfectly fitting.

Candidate 2: Manuel "Manny" Rezentes

Rezentes was a well-known working professional in the Honolulu music unions and performed in the hotel circuits during the peak of the "Tiki" and Big Band hotel era.

• Birth/Death: Records indicate a Manuel Rezentes who died in December 2001 (a notable year for the passing of several Hawaii music legends).
• Why he fits: He was a "musician's musician"—the kind of guy who played nightly residencies (like the King Kam) rather than touring internationally. This matches the note's description of a steady performer rather than a celebrity.

Candidate 3: Manuel Ferreira

• U.S. Army Veteran. Served in the Hawaii Department (likely where the USQMC horn originated).
• 1892–1983. Born earlier, but definitely active in the music scene.

Comparison for Verification

Detail	Manuel Silva Jr.	Manuel Rezentes
Active 1960s?	Yes, high-level professional.	Yes, active in music union.
Instrument	Brass (Trumpet/Cornet focus).	General Brass/Musician.
Shriner Link?	High. Many Silva musicians were Aloha Temple Shriners.	Possible, common in the trade.
Connection to Joe Royal	Professional network / Shrine circuit.	Professional network.

King Liberty Trumpet Years Built: 1920 - 1932

Front Slide: Tuning Bore: .448

Key(s): A & B-flat

Rear Slide: A/B-flat

Pitching: LP

Tuning Lock: Retaining ring

Bell Material: Sterling Silver

Bell Type: 2-piece

Name(s): King Liberty Silvertone, Liberty #1 Silvertone

Can't wait to get this, look at those valves, no striations from wear, they were replated at some point. Looks like a total closet queen, still has 3rd valve stop rod nut(should be 2, but better 1 than none)

https://www.ebay.com/itm/137094569413

It seems the collaborative concurrence is that this is a trumpet, but all the build details still apply.

It seems to be from the turn of the last century (1890–1915). The physical evidence on the hardware is too specific to that era of German and Austro-Hungarian craftsmanship to be much newer.

While the measurements corrected the pitch to a standard Bb, the construction methods are the "time stamp" for that 1890–1915 window.

Why 1890–1915 is the "Sweet Spot"

Feature	Technical Historical Context
Clock-Spring Barrels	These began to be phased out by the more modern "S-linkage" or Minibal systems by the 1920s.
Hexagonal Casings	This was a high-labor, high-precision feature of the late 19th-century master shops like Ed. Kruspe and C.W. Moritz.
Back-to-Back C Brace	This decorative "Lyre" or "Scroll" style was the peak of the Markneukirchen/Graslitz aesthetic during the pre-WWI "Golden Age" of brass making.
Nickel Silver Trim	The use of heavy nickel silver on the braces and valve caps (instead of just thin brass plating) is a hallmark of professional-tier instruments from that specific era.

The "Turn of the Century" Master Build

After WWI (the 1920s), many of these German shops moved toward "simplified" designs to lower costs. The fact that your horn has ornate bracing and hexagonal spring barrels suggests it was built when labor was relatively inexpensive for master craftsmen but the demand for "prestige" mechanical features was at its highest.

Finding a 110+ year old instrument where the valves are "crisp" and the slides are "free" is incredibly rare. Most horns from this period have "red rot" or seized rotors that require a specialist like Josh Landress to fix.

• The Physics: At 136 cm (53.5") of tubing, it will have that classic, dark German Bb flugelhorn or "Konzerttrompete" sound.
