Nikon began the production of cameras with a line of Nikon rangefinder models. The first one was the Nikon (AKA: Nikon I) launched in 1948. On this camera, Nikon copied the Contax rangefinder mount designed before the war by Zeiss Ikon and introduced with the Contax I.
Whether related to patents, differing initial engineering decisions, or by mistake, the rangefinder coupling of its lens mount was slightly different than that of the Contax. The result is that the wide angle lenses, because of their wider depth of field, can interchange between the two types of bodies, but the standard and tele lenses cannot. There are Nikon versions and Contax versions of all focal lengths above normal. This proves that there was, indeed, an acknowledged difference in coupling. Nikon apparently made an engineering decision that the disparity was not significant at wider focal lengths. However, there is some discussion as to whether the problem is also apparent for normal lenses at close distances, as discussed by Dr. Bruce E. Sirovich in a Nikon Historical Society Article.
The original lenses for the Nikon rangefinder models.
Nikon also made some these lenses for the original Contax mount. They are marked with a C on the barrel, unrelated to the red C on the front ring of the coated lenses.

Reflex housings Edit
Nippon Kōgaku made its own reflex housing for the rangefinder cameras, in two main versions.
