Had a couple bodies that needed attention.
Patient #1 was my FM2n. Let my sister use it, and, since I'd been using the motor drive, she didn't realize that she needed to use the firing button on the MD-12. Instead, she tried to fire the shutter with the normal shutter release. Wouldn't work. So, she starts advancing the film. Apparently, at that point, the double exposure prevention cam bent out of the way and allowed her to advance a frame without firing it. Took the baseplate off, and bent the cam upward, so it would positively engage the notch on the motor drive advance shaft assembly. Seems to work fine now.
Patient #2 was the Pentax SV. Ever since I got the camera, the shutter speeds had been erratic, especially in the slow speeds, since the curtain sometimes wouldn't close after exposure. Took the baseplate off, and adjusted the tensioning screws until the shutter fired reliably at all speeds. Now just needs to go in and get refoamed, since the light seals (or what's left of them) look original. 46 years old original, to be exact.
