I just picked up my 620 Kodak Monitor from Carol Flutot this afternoon. Carol did a CLA on the lens and shutter and it sure looks and works nice! It has a coated 101mm Kodak Anastigmat Special in Kodak Flash Supermatic Shutter. There was some fungus on the rear lens element, but Carol cleaned it off.
I picked the camera up on eBay for about $20.00, including shipping.
Tomorrow I'll try it out with a roll of J&C (trimmed 120 spool) Fuji Acros.
