Leica 40mm f2 Summicron-C 2553870

This Leica 40mm f2 Summicron-C prime lens (Black), #2553870, is in below-average cosmetic condition with significant wear from normal use. I rate it cosmetically an (8). The focus ring is smooth, but the aperture ring is quite stiff. The aperture functions properly, but there is some oil on the aperture blades. The glass is clean and clear with no haze, marks, or fungus. There are a few faint specks of dust inside, but they do not affect image quality. It is for Leica M mount. This lens includes a vintage plastic Leica rear cap. This lens is ready for use! Please refer to the photos for details.
