Rodenstock Grandagon-N 75mm f/6.8 MC Large Format 4x5 Lens, in Copal 0 Shutter.

Covers 4x5 with plenty of movement space.

Condition is excellent. Optically unmarked, couple of tiny specks of dust inside but nothing that will impact image quality. All shutter speeds seem accurate in my usage, the slower ones I've timed using a phone app and are spot on. Comes mounted to a metal Linhof size board. In my experience, doesn't require a centre filter with black and white or colour negative film (samples are Ektar and HP5), I have not shot slide with it. 

Takes 58mm filters. Comes with original push on caps. 

Any questions, let me know.
