I decided to try my hand at a little CLA of a Kodak Signet 35 rangefinder camera. Oiled some of the gears, filed a mechanism that wasn't catching, etc. I also took the liberty of scrubbing every surface (minus the mirror) of the rangefinder apparatus. You can now see much more clearly than before, and the triangular patch is now visible. However, the patch is projecting a double image slightly below where it should. Any ideas? I managed to bend the focus glass (?) a little to get it almost correct vertically, but it's still seeing double. Any ideas are appreciated. If you want me to take a picture of anything in particular I can.
