Leica 9cm f4 Elmar, Bakelite Case 837957

This Leica 9cm f4 Elmar Lens, #837957, is in great condition with minor handling wear. I rate it cosmetically a (9+). The aperture ring is a bit stiff & rough, but the aperture functions properly. There's some faint oil on the 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. The focusing helicoid is smooth. This lens includes front & rear caps and a Bakelite Leica case. It is for Leica screw mount/thread mount (LTM) and other E39 bodies. Please refer to the photos for details.
