Yashica Mat 124 Shutter release Parts
Francesco,
Exactly which part is broken? The lever that is activatd by the release button is riveted to the lens plate. ...and would likely need that entire plate. That lever operates a ring shaped lever that surrounds the taking lens mount on the rear of the plate. I have the plate assembly including the levers, shutter and both lenses in the junk box. If you want a photo, e-mail me : jfisher (at) plateautel (dot) net. Shutter doesn't seem to work - but for parts...
