Soviet 50mm f3.5 Enlarger lens

This Soviet era 50mm f3.5 enlarging lens is, as the name suggests, for use on an enlarger or with bellows. Even though it is Leica thread mount, you can't directly mount to your camera and expect useful results; there is no way to focus it. Some cosmetic wear to the front, there is some dust and minor hazing in the optics (shouldn't impact function) minor wear to diaphragm blades.
