I recently bought a Pentax ME Super as my first ever film slr. Upon inspection the winder arm and shutter seem to have problems.
The shutter appears to be stuck in the open position (see picture) but can be moved to open by pushing the small lever inside of the lens mount to the left of the mirror. When the lever is released the mirror goes up with it and won't stay in the usual position.
The film 'winder' is not jammed as many posts here seem to suggest; it moves freely but I think too freely. There is no friction on the arm and when I removed the bottom cover on the camera and moved the arm, nothing moved in the mechanism at the bottom of the camera.
How can I fix this? Any suggestions welcome!
