Rare Pre-war! WW2 Fed 100mm f6.3 lens (Serviced)⭐️

Interesting rare lens produced between 1938 and 1941 at the Kharkov Labor Commune in Ukraine. So about only 8,000 of these were made! (and less that are actually working). Pretty sharp at 6.3. f/36 smallest aperture. M39 LTM screw mount. Can be adapted to most digital cameras. Pretty good condition (for how old it is). NO fungus, no haze, no scratches. Feel free message for questions.
