Mamiya 7 150mm Lens: Replacing a Bent Filter Ring

This 150mm Mamiya 7 lens was attached to a Mamiya 7II and it took a fall. Fortunately, the lens filter ring absorbed most of the energy and the camera and lens functions are fine.
Although I can straighten these bent rings up pretty well, my client requested that I replace the ring with a new stock part. Also, the name ring was replaced. No matter how well the ring is straightened, they may be some very small signs of the previous trauma and I think my client did not want any memory of the sad time his camera dropped to the floor.
Photo two show the lens in my filter ring straightening tool ready to get fixed up. It was necessary to straighten the filter ring to proceed with disassembly of the lens. Photo three shows the lens ring straightened. After removal of the parts, new bits were installed and everyone is happy.
