I am repairing a Junghans A12 movement and the fly pinion is damaged.It is a 7 leaf pinion and I need a replacement or repair. Is it possible to repair the pinion , and how is this done? Also is it totally necessary to have a fly inorder for the strike to correctly work. I am new to this so I appreciate any suggestions. I have tried to find a replacement arbor and pinion but no luck so far. Thanks for any suggestions.
