I have had this camera for a number of years and received it in somewhat bad shape. Craziness has overtaken me and now I want to try to fix it. The shutter blades don't all seem to be in correct place and that little tab, the small bit of metal that allows the camera to sit correctly in a vertical alignment position (the one on the front cover of the body) is missing. If you have a parts body or that part available, let me know.
