RZ67 110mm f/2.8 Lens: Restaking a Broken Cocking Ring Pin

This Mamiya RZ67 110mm f/2.8 lens came into the shop locked up tight. Upon disassembly, I found that the locking pin for the rear cocking ring had broken off from its spring base. Years ago, I would have just reached over in the parts bin to replace it, but with Mamiya parts supplies diminishing, I decided to restake it to the base. A watchmakers staking tool makes this very easy to do.
