This is a large format lens, OLOR No.6 serie 11a 200mm f5.7, made by SOM-Berthiot in France. The lens has no fungus or haze, but there are some minor cleaning marks, slight dirt on the edges, and a small pinpoint scratch on the rear element. The aperture blades are in good condition. It comes with a flange, making it very easy to attach to a board or other mounting. This is not an F-mount lens, despite the category. *As this is a very old item, please refrain from purchasing if you are sensitive to such conditions.
