I'm in the process of scanning the old family Kodachromes. They were all photographed with an old rangefinder that my parents had. I wanted to find out what it was but my parents didn't remember. The best I got from them was it might have been a Minolta or an Olympus. It was probably purchased in 1957, had a flash and quit working sometime in the 70's. Camera store said it wasn't worth repairing so they pitched it. It would have been something that was readily available in St. Louis and been affordable for a letter carrier. Any ideas as to possibilities?
