Noob question about MOT. (which wires?)

So, pulled one out of eCycling. Looks to be pretty standard. Has three secondary wires one that is spliced to make two connections. One of the leads has a plastic shield on the connector. Another lead from the spliced one also does. Are those two (the shielded) the high voltage? Looking at magnetron schematics, it appears to be that way, and that I'd ignore the single shorter lead with no plastic shield:

I picked up a transformer with basically 4:1 step up. Surplus place said it was designed for a 500v primary. The manufacturer won't release the specs as it's "propreitary to the OEM." I figure with a nominal 117v primary I'll get around 500v unloaded. Add a full wave bridge and I'm around 700 unloaded. The only filtering I can see would be a choke? for something like 807s 811As that can handle that high a B+, is a single resistor-choke acceptable somewhere between 7-14H?

Store said this was a several kilovolt transformer for a laser. Research says it comes from Cooltouch cosmetic laser, but I can’t find anything else about it. It appears the white leads are primary (and they’re floppy like rubber hoses) and the terminals on top secondary. I can’t find anything else. I can certainty inject a 1 voltish AC sine wave and measure what comes out the other end but any insight appreciated
