Wakabayashi Motor Industry, Osaka city, Daiko-Cho, 1952-53
若林自動車工業
Another small company assembling machines using engines from another supplier. Wakabayashi Motor built and sold two models: the Sylvania (シルバニア号) and the Empire (エンパイア号) which was a single cylinder ohv 148cc four-stroke, with a three speed gear box. The Sylvania is listed as one of the models produced on the Japanese language Wikipedia site at this link but I have not been able to confirm it elsewhere.
