Konica Auto 1.6's finder is almost the same except it has a flash contact on the back side.
When I received the camera, the finder's front glass had a small chip at the bottom. When I was removing the front glass, I broke it.
I took the front glass out from another finder I have and replaced the lens. Also, the small mirror was unglued from the old age and it was found inside the finder undamaged. I glued it back. The finder has been cleaned and adjusted. The finder works as good as new.
