This is the same as our L2084 (now sold out) except something doesn't work. Made for the Revere 35mm stereo cameras. Lenses are in mint condition but the shutter may not cock correctly, or both iris diaphragms may not move in tandem, or some other mechanical problem. Here's a great opportunity to get two good 35mm f/3.5 camera lenses with coated optics as well as a mechanical challenge for a very low price. Great educational item.
