Looking for enlarger lens mounting disc.

[Silver Spirit]

Hello everyone.
I'm trying to get into darkroom printing and have recently purchased a "Minolta Enlarger II." Upon assembling the enlarger I noticed it's missing the lens mounting disk shown in the manual. I'm trying to find a replacement or compatible alternative.

Replacement parts for LPL, Omega, Beseler, and De Vere enlargers.

This is where I would start. Not common in my experience.

Looks like a relatively simple disc with a 39mm hole to mount the lens and two drilled holes to accept screws.

If you are handy, you probably could fabricate one out of sheet metal without too much pain.

Also,if you can scrounge-up the exact specs, have one 3D printed.
