Mamiya C 80mm f/3.7 Lens: Replacing a Missing Sync Contact Assembly

This Mamiya 80mm f/3.7 lens came into the shop for routine shutter cleaning and I was advised that the customer had attempted a repair. What I was not told was that the entire sync contact assembly (5 pieces) was removed from the shutter! Fortunately I had replacement parts. This is not a common lens (was a “budget” model mostly sold with C220) and uses a Copal 00 shutter with no parts being interchangeable with the Seiko shutter used on all the other C lenses.
