My first professional 35mm camera was a Nikon Ftn purchased in 1968 while serving in Vietnam. That was has long ago left my care. About a year ago I bought a 1973 model of the same camera. There are 2 screws missing that have no bearing on the operation of the camera. One is a screw that holds the "Nikon" nameplate on the camera and the other is a screw that holds the faceplate on the Ftn finder. Their not being there makes me crazy. Any idea where I might find replacement screws?
You can get replacement screws, but probably not in the same style. It seems camera makers used custom screws for everything. If you don't mind replacing all the screws that hold the nameplate in place so the thing looks 'factory' then try https://www.mcmaster.com/screws/ I find it easiest to pick the right size (i.e. M1.5) from the selector panel on the left and then look for an acceptable length and head style.
Nitroplait's suggestion to get a sacrificial camera is a good one -- it may cost less than ordering the replacement screws. You don't need an F, you can probably find 'close enough' screws on an old seized up Nikkormat, Miranda or Petri. You can remove the screws you need and then sell the camera on to ebay at the same price, again for 'parts.'
I bought an FTN finder from KEH described either as bargain or as-is, don't remember which, that, when it showed, up was in better condition than what I bought it to be a parts donor for.
Thanks for the great suggestions. It is driving me crazy, so I will get it sorted out. I've bought and sold much over the years and have given away quite a bit of stuff, including hard to find bits and pieces and perfectly good cameras and lenses. When selling, I always deliver more than promised. I'm counting on Camera Karma and feel certain something will turn up. What I'm looking for is not a unicorn.
