Mamiya 7: Replacing a Broken Wind Lever Return Spring

This Mamiya 7 came into the shop with a wind lever that would not return. Not an uncommon issue and is usually caused by a broken wind lever return spring. To access the spring for replacement, the top cover, speed control board and the counter needs to be removed.
Photo two shows the counter assembly with a date code of 4/9/1997 stamped on it. Seems about right as the camera itself had a date code of July 1998. It is not that usual to have camera parts with a date code stamped on them. Mamiya did this also with the Mamiya 7 rangefinder assemblies.
Photo three shows the broken spring being removed from the camera. Photo four is of the new spring before installation. The long curved part on the right is always the point of failure.
