The shutter speed dial is not functional. I believe something much have broken from an impact so that the dial is not able to set shutter speeds in any predictable fashion. As far as I know, the metering and exposures are working, but not able to test with the shutter dial broken. So, can't be used in a manual fashion because unable to manually set speeds or even into auto mode.
The mirror, viewfinder, shutter are working correctly. It's currently in B mode, so could be used as a night photography camera, or pinhole camera.
