Need help opening/oiling vintage Kenmore 158 sewing machine top
I picked up this beautiful vintage Kenmore 158 sewing machine from Facebook Marketplace today. I think it might be a 13200 model.
The machine runs perfectly when I press the foot pedal, but I haven’t fully tested it with threading yet.
The seller said it originally belonged to her grandma, so before actually using it I wanted to clean, dust, and oil it properly. I watched a couple of YouTube videos and TikToks showing how to open the top for oiling, but I can’t get the top to budge even a millimeter.
Things I already tried:
Moved the metal piece used for bobbin winding (one YouTube video suggested that) - also in the manual I downloaded online says like that.
Checked all around for screws, but I can’t see any
Tried gently lifting/prying the top, but no luck
Does anyone know if I’m missing a hidden latch or screw on these machines? I attached front/back/top photos.
PS:thismachine only came with the standard presser foot and no accessories. Does anyone know a good place/website to buy compatible feet and attachments for these old Kenmore machines, including the buttonhole attachment/template?
TIA!
