Hard to find Russian M39 mount 100mm Lens F6.3 in a decent shape .Optics are in decent shape with light dust specs and light wipe marks may have some light hazing spots and Aperture mechanism works as it should.  Lens looks cosmetically decent. Focus is jammed up doesnt want to turn at all. 

You will need to get the lens cleaned lubed and adjusted before you start using it. 

Selling As is!
