Found today in local secondhand (junk) shop, bought for a pound, a Russian lens, an Industar standard 50mm F3.5 from about 1959 made by the KMZ plant in the USSR. I did search around to see if they had the Zorki camera body to go with it, but nothing showed up, I may check with them again.
This lens was the replacement for the earlier collapsible standard 50mm F3.5 lens based on Leica's pre-war design, and retained the same glass elements in a much more substantial aluminium focusing mount. They were supplied on mid production period Zorki cameras till about 1963.
This one appears to have been a USSR home market version, no western script on the markings, so probably it was never officially imported to the UK by the importer, TOE Ltd, (Technical & Optical Equipment).
The general condition of the lens is reasonable for its age, the glass elements are fungus free, but it has a very slight haze under bright light, very few marks on surfaces, the coating is sound. I will test it on the Periflex, same M39 mounting.
The slight light haze is a known issue with Industar lenses, nothing much to worry about in B/W, where a yellow or red filter, and medium aperture makes sure it does not show. Open aperture is generally a bit soft.
It does affect colour slides a bit more, it lowers saturation, but works fine for portraits, and is quite satisfactory for colour prints, where there is a very faint glow to brighter highlights. Sharpness varies with examples, as usual with USSR productions, so a test film will be needed to check this one out.
I think I have a spare Zorki camera body that it can go on, after testing out.
