This rare vintage Schneider Tele-Xenar 18cm (180mm) f/5.5 telephoto manual focus lens has a 43mm screw mount. I believe this originally had a Reflex Korelle or an Exakta mount and was changed at some point. To fit on what, I have no clue. There are a few scuffs and scratches on the exterior of the barrel. Its focus and aperture adjustments are both smooth and its glass is free of any fungus, haze, or separation to its elements. There is no oil on its aperture blades.
