Neat little old timey anastigmat to play with. This is the early one with both a normal f stop scale, and mm of opening on another scale. Kind of unusual. Made sense on the Protar's but serves no real purpose here.
Nice clean glass. Beautiful smooth circular aperture.
What I'm showing in the photos is that you can easily accomplish with your Zeiss what Wollensak did with their diffusion ring on the Velostigmat Series II. You seperate the front two elements, then when it screws back in, you leave the same gap.
Anyways, I know it's not worth much. How 'bout $45 bucks. Sorry, no flange.
