This is a BIG lens: 95mm filter, 4.5" mounting and about 7" long. I do not know the coverage but it should be at least 8x10 (there is no data on the lens).
It appears to be a Petzval design; there is a group in the front and one in back and a lot of air in between. There is no aperture nor slot for stops.
The focusing pinion is missing but otherwise the lens is in great shape. It is easy to focus by sliding the lens in and out. There is comfortable friction that holds the lens in place. The glass is clear and scratch-free
