This is a Kiron version stuck wide open at the moment, the auto pin is loose so if you hold the lens mount up it drops in and visa versa, not sure if that's the problem or just part of it, anyone know how to get at the mechanism, there are 4 small screws below the aperture rotate ring and 3 above it, I can use it wide open but it would be nice to get it working again if I can without knackering it permanently |

The auto pin is that loose, depending where the A/M switch is set.
