Tokyo Orion Industry , Nagoya, 1953
Tokyo Orion is listed in the Japanese language wikipedia site. In 1953 it is listed as producing two machines, one called the Orion (オリオン号) and the other one was called the Linnet (リンネット号). Tokyo Orion was actually a bicycle manufacturer, and so I'm assuming both machines used clip-on engines purchased from someone else and were each mopeds of some sort. The only source I've found (meguroworks) seems to indicate that the two models had different makes of engine. In the photos you can read 'Linnet' in English, and this was a 60 cc two stroke, most probably a Gasuden with a custom engine cover.
