Had a good evening cleaning the other two. The Om-2s program lights right up with a new battery, and other than needing new seals, should be ready to go. No silvering or gummy old seals. I put the 28mm on it for pics. The OM-10 cleaned up well but has a couple glitches. The power button under the rewind knob is really sloppy, not clicking into each position and traveling one direction a lot farther than needed. It is so sloppy that I need to check the light meter to make sure it is on. Which leads to the other problem, the shutter will not fire. I am hoping that once the switch is repaired, the other issue is related. It also needs new seals. I would like to find the manual adapter for it also. It has the 1.8 50mm for its beauty shots.
