Russian Jupiter-11 135mm 1:4 lens by KOMZ, with matching plastic end caps. It has a 39mm screw thread mount. The focus works, but does have a little stiffness to the movement. The aperture functions – there is some oil residue to the iris blades. The optics are scratch and fungus free, but there is minor internal dust fragmentation and haze when held against a strong light, as per the photos. In good, used cosmetic condition, with some surface whitening and pitting to the metal barrel.
