Here is a nice big lens from Wollensak with a modified Petzval design. This lens has great coverage at 8x10 and will fit on a 4x4 lens board. It has a studio shutter and the aperture has a wide range of stops from 5 to 45.
This lens is in great condition with clean, scratch free glass, light cosmetic wear and a smooth aperture and shutter. The aperture has a slightly irregular shape when stopped down but it does not affect performance of the lens.
This is a nice one.
