That way, buyers would know that such a Nikon had been corrected to conform to a standard film advance.
I find it odd that Nippon Kogaku wanted a product for world wide sales, no different than the other up-start miniature camera makers in post war Japan and yet played around with 24x32 and 24x34 formats.
The idea of getting more photos from one roll of film might have sounded great in Japan that was rebuilding from the destruction of war and wages were low but it was a bad idea to go against the mainstream, even for fitting full frame in Kodachrome cards alone.
Yes, I know that even German camera makers had made cameras in 24x24 formats ( Zeiss and Robot, for example) but these were not mainstream and sold poorly and or were for specialised applications.
