Fuji Shokai, Nagoya, 1952
不 二 商 会
Fuji Shokai is listed in the Japanese language wikipedia site, and also listed on page 144 of my copy of the Japanese Motorcycle History, 1945-2007. It appears to be a one year only company and the text under the photo indicates that it used a single cylinder, OHV 150cc engine made by Olympus and used a frame of their own design. The machine was called the OMC (OMC号).
