I found one at a yard sale last week barely working. I have been told most techs won't touch it so I took a stab at it. Pulled the shutter assembly off the body and after an overnight soaking in my ultrasonic bath serviced it. While the shutter was off I serviced the focus helicoid. I then checked the rear baffle to shutter blades timing and adjusted the mirror seat to get infinity. After a quick film test shooting at f/2.8 to verify focus. I then went out this morning for some real testing and now have a roll hanging to dry in the darkroom and all frames look sharp and contrasty under the loop. This is a fun camera to use and I plan to pick up a 35mm and 85mm for it as well as a couple of magazine backs.. Next up will be the Super B and Super BC with their mag backs..
