Schneider-Kreuznach Componar 1:4.5 / 75 Adapted Square Bokeh Art Lens. Condition is Used, may be some superficial dust, glass is clean, aperture blades are clean. Lens is attached to a machined M42 adapter and comes with an M42 - M42 12-19mm focusing helicoid. If you plan on using this with a DSLR / SLT / Mirrorless camera for the square bokeh it produces, be sure to check your flange length, you may need an extension tube along with an adapter to be able to use this lens.
We've never seen this lens or any other period Schneider enlarging lens in a focusing barrel, probably where most of the value/interest is. Ring is riveted to the lens board so if your interest is in mounting it on another board you will have to drill out the rivets.
