| A nice clean lens assembly manufactured by 3M Company. Front lens clear diameter of 28mm, rear lens clear diameter of 34mm, multi-element, with coated optics. The assembly was apparently made to attach to a camera, as there are timer (T) and bulb (B) markings on the 2-position knurled setting ring on the barrel. There is a 16X marking on the front. The internal aperture is preset at f 5.0. The assembly measures 50mm long x 55mm wide, with a satin black-enameled brass barrel. Supplies are limited! |
