This was a quick, fun little project. I took apart this Yashica MG-1 (1975 model) for a friend. It had stopped working recently and he wanted me to take a look at it and it had lots of bad wires and a stuck shutter. To un-stick the shutter, I had to take the whole lens block off from the body, and reset and oil it, then the wiring was a mess so I put all new wires in and soldered them better than the originals. I bet this camera will work for another 39 years.
