Nikon Stereo-Nikkor 3.5/3.5cm Set in Case f. Rangefinder

The rarest of all Nikon RF lenses, only about 170 units were made, at least 28 of them have been destroyed because of Japanese tax on inventory.
The lens produces an ortho-stereoscopic image from 3ft to 10ft; above that distance, the prism attachment should be used to maintain correct stereo imaging until infinity. The set includes a stereo Nikkor 3.5/3.5cm no.241934 in near mint condition with clean lenses, all matching accessories like prism attachment no.679185, a stereo finder, hood, cap, film roll, all of them are in a matching leather case, all items are marked with 'Nippon Kogaku Tokyo' and 'NKT' logo.
