I believe I've just learned a lesson: ask every question you can think of before buying a vintage camera off ebay. I just won a Spotmatic body for admittedly a very cheap, even throwaway price, and it was described as being in excellent working condition. Of course, I open the box, and the first two things I do are fire it at 1000 and a few speeds slower to see if it seems to fire accurately, which it does, and then check the inside. The first thing I noticed is that the foam lining that the mirror bounces off of is completely decayed and gone.
My question is, what issues does this cause if I don't fix it? Also, it seems like everybody wants $70 and up to CLA or do anything to a film camera these days, which is not worth it for a Spotmatic (if I have to spend $70+ on the body alone, I'd buy a better body than a Spotmatic). How difficult would this be to repair myself? Is it worthwhile? I paid $17 shipped for this body. Thanks for any advice.
