It is a known fact that Nikon got its start by copying Leitz and Zeiss lenses and later cameras to enter the photographic market. The upcoming WestLicht auction in Vienna shows another example of Leica tech used by Nikon.
Nikon Stereo Nikkor 35mm f/3.5
The Nikon Stereo-Nikkor 35mm f/3.5 outfit consisted of a stereo lens and stereo prism for the Nikon rangefinder cameras. Introduced in 1956, it bears more than a close resemblance to the Leitz Stereoly, first introduced in 1931 and later replaced by an improved model in 1954.

In either case, this stereo equipment produced two half frame stereo images in place of the standard 35mm frame. Stereo viewers and projector accessories allowed for stereo viewing of the images taken.
Thus we have another example of the influence Leica has had on other manufacturers over the years. Leica cameras and accessories remain the most copied photographic equipment in history.
