Forty years ago, I had a Mamiya C3 with a 105mm f/3.5 lens. The lens and camera are long gone, but this case for the lens has been kicking around ever since. It would seem I never throw anything away.
The kit includes the leather case, a cap for the back of the lens, a cap for the camera body, and a mask for the ground glass. If you can use it, it's all yours for the cost of postage and a small donation to APUG.
