From my information source, this appears to be a pre Ww2 camera. There were several Mitchell copies, One is Seiki Kogaku (精機製作所), and the other one is Doi Kosaku-jo (土井工作所). The Doi was a rip-off like the post war Russian cameras.
Seiki Kogaku ones had produced pre-war era the most, were the famous for the optical printer and animation camera and was very popular; even exported to the US for animation studios. Apparently the NC clone was a licensed design but by 1952, the NC patent had expored in many countries.
Seiki Mitchell was initially the copy of the NC, but Seiki had learned and taken the idea of Silent Bell (B&H), quiet pull-down claw system, it's not same as NC model, and they had the problem with the stainless steel material film gate that had to revise to the different design. Unfortunately, not many Seiki Mitchell exist in Japan, most of were destroyed or taken by the Allied force.
For your information, Seiki Optical Kogaku established in 1933, and their still camera became Canon brand in 1937.
