Who knows anything about this camera? A coworker gave me one with a 53mm lens today...it came from his grandmother's attic and he was going to take it to Goodwill before he realized I have a collection in my office (an unintentional, but very effective strategy for attracting more cameras, by the way!), and might appreciate adding to it. I'm not sure how well it works, though. With the back open, when I fire the shutter I can hear the mirror operate, but there is a flat barrier that sits at about a 45 degree angle that looks like it needs to move along with the mirror in order for the light to hit the film. It doesn't move, and I'm not sure what to do to repair it or if there is something I'm missing. Any ideas? Any info on this camera would be greatly appreciated.
