Just to clarify things for you guys, it was sold as working, but sold "as-is" (he said the focusing screen was dusty, which it was, as well as the mirror). I have contacted the seller, but the amount of money to ship it back isn't worth it anyways. I checked the pin on the right side, and it moves in and out fine. I put a spool in the top chamber, and even a now ruined roll of film to see if I can make the counter work. I have also spun the silver rod with a gear (although I did this with the camera open). I just can get no movement in the film counter at all.
My brother is a mechanical engineer, so I've sent him the repair manuals and we may try to tinker with it when I see him for xmas, but I obviously wish there was an easier fix to this.
