This Goerz AM. Opt. Co. Dogmar 7 1/2'' (190mm) f/4.5 large format barrel lens comes with its mounting ring. There are a couple of scuff marks and some minor finish loss on the barrel's exterior. Its aperture adjustment is smooth. There is a light haze inside of it, but it is free of any fungus or separation to its elements. There is no oil on its aperture blades.
