The seller told me that this Leica IIIC has been overhauled recently. All functions work smooth and accurate. The shutter speed dial is provided with a copper ring, as shown on the pictures. Not sure why that might be useful.
The lens is optically in great shape. Most of these Summitar 2.0/50mm lenses have haze or fungus; this one is clear and clean.
This set is ready for use and is provided with a lens cap.
