This is a relatively large brass antique camera lens measuring approximately 4.5 long. The lens states Calhoun Photo-Materials Co.
Rapid Perspective and 14 x 17. The F stops are 8-64 and it seems to work well. There is some yellow cracking on both lenses, moreso on the larger bottom lens. There is dust inside the lens as well. We have 3 other antique camera lenses for sale by Dallmeyer, V.
