Motor Shokai, Tokyo, 1928-1939 ?
モーター商会
Motor Shokai, better known as M.S.A., initially at least used J.A.P. sv engines imported from the U.K. with chain drive and a 2 speed transmission in their tricycle utility vehicles. By 1936 they were possibly using J.A.P. copies as the engine case shows their name rather than J.A.P.. They also appear to have made a motorcycle in 1928, but other than it being a belt drive, and looking a lot like many U.K. models from the early 1920's, there is no other information available currently.
