I haven't checked the size and it's not clear whether any take a knob, but
something like these (Mouser)?

Subject: [M100] M100 Contrast potentiometer (VR1) replacement
Does anyone have a suggestion for a replacement contrast potentiometer for a
model 100? I have a machine that was working until someone ‘over-adjusted’ the
contrast knob and it now spins freely, and therefore doesn’t work. It’s not a
mechanical issue with the screw and the knob, but rather inside the mechanism
I tried a quick scan of Digikey but I can’t find anything with remotely the
same form factor. Wondering if anyone knows of a source for these, or has
managed a repair with a substitute?
Thanks for any guidance.
