I found a black Nikon F with an eye level finder in a thrift shop last week afor $150, so I snatched it up.
It appears fully functional (test roll waiting for development) but the prism mirror has a chip in the glass and a vertical line down the middle. It doesn't affect functionality, but I'd like to fix it if possible. Of course, non-metered finders are ridiculously expensive (more than what I paid for this whole camera usually) and I haven't been able to find just the parts, but I did come across this drawing of a metered finder, which makes me wonder if the prism parts inside would be swappable
So does anybody know if this is doable? before I buy a parts finder..
