Brass Petzval Lens brand_Horseman The Nikon 35mm f1This is an unmarked Petzval design brass lens for large format cameras. Likely from a projector there is no diaphragm or slot for Waterhouse stops it features rack and pinion focusing and pretty decently clean glass, free of fungus, with minor marks from cleaning over the last, like 100 years or more. Focal length and aperture are unknown. Includes a threaded flange for mounting to a lens board (not included). Will cover 4x5.
