Wray London 5.5" f5.6 for 4x5 7203 and the whole thing runsThis brass Wray London lens is designed to cover 4x5, despite its tiny size: it's less than 4cm long. It's a 5. 5" lens (about 140mm) and has an almost perfectly circular diaphragm with apertures down to f64. Barrel has some tarnishing and surface wear, aperture control is a bit tight towards the smaller apertures, but the optics are quite clean. Includes a threaded mounting flange.
