I've been buying and selling cameras since the mid 1990's, usually when I'm not busy doing my photography, before this one, I'd give them a good clean, and make sure there working perfectly, but this one needed a little bit more work than a clean, although the body was clean, the spring was weak in the film rewind knob, the baseplate was scratched, but mainly the prism was corroded, if you have the OM1/OM2 that hasn't been affected, your very lucky, or it's been corrected, the only option is a new prism, luckily all OM's even the later 10,20,30 &40 share the same prism, but they didn't use the foam that corrodes.
First the top cover has to be removed, there's a few videos on YouTube that shows it better than I can explain in words.
This is what the corrosion in the viewfinder looks like
This one was toast, luckily I had an OM30 that I bought for spares for the princely sum of, £13
With the top cover off, you can see the corroded foam
The hotshoe bracket needs removing, all the black gunk needs removing, it's not a nice job, but I took it slowly, and a final cleaning with Isopropyl alcohol on cotton buds and sponge applicators, I removed the focusing screen, as it makes it a little easier, although I replaced it, as it did have a few marks on it
