KMZ Industar-22 5cm f/3.5 П 'Rigid' - LTM

A somewhat rare 'rigid' version of the Industar-22 normal lens for 39mm Leica thread mount. Focusing moves evenly. No excessive dust inside optics, front lens has some cleaning marks. Oil marks on aperture blades, but these do not affect use. Apparent signs of use and ageing.
