I've never owned any Pentax gear so I have no idea if it's a fob or badge that came with a camera, or some sort of ball marker for putting. Any one know?
The shutter will not cock without film loaded for dry firing. One can rotate the frame counter past 0 while closing the camera back or use the shutter key to accomplish linking the shutter cocking mechanism with the body's cocking lever for dry firing without film loaded.
