Leitz very rare early Leica screw mount lens 5cm 50mm F:2 Summar RGD Nickel, c.1933 nice condition

Nice and very rare lens Leitz for the Leica 35mm rangefinder cameras with M39 mount. It's the 50mm F: 2 Summar in rigid mount and Nickel finish, code Leica SUMAR with rotating mount. The serial number of this lens is 186539. It has rangefinder coupled mounts. For it's age (nearly 90 years! !) it's in very good condition, as is possible to see from the pictures. Hard to find so old lenses in these condition. It's in working order, the blades are oil free. Its hase some dust inside, some cleaning marks and haze inside (normal for its age) . It comes with rear and front caps. It's particular that the lenses are coated, probably work done in Leitz in a later period. A very rare lens a great item for the Leica collector.
