This is a fun lens - Carl Zeiss Jena Tessar Nr. 703327 120mm f2.7 in a Universal shutter. The shutter is slightly slow but consistent. The glass is clean, I had to look several times to find the faintest of faintest cleaning marks on the front edge but otherwise the glass is super clean and free of scratches or defects. The aperture moves smoothly all the way. It is on a 4x4 board that's been shaved on the edges so it works in older Graflex models. It does not have a flange and is "screwed" securely in to the wood board. It fits any camera with a Deardorff/Graflex 4x4 board. $625 + shipping.
