Leica 5cm f2 Summicron Collapsible Thorium 1020393

This pre-owned Leica 5cm f2 Summicron collapsible prime lens (Silver), #1020393, is in good cosmetic condition with minor handling and edge wear. I rate it cosmetically a (9). The lens extends and retracts properly and the aperture ring is smooth, but the focus ring is a bit stiff. The aperture functions properly, but there's some faint corrosion on the blades. The glass has no haze, marks, or fungus, but there are some faint specks of dust and debris inside. It is for Leica screw mount/thread mount (LTM) and other E39 bodies. It comes as-is with no additional accessories. This lens is ready for use! Please refer to the photos for details.
