Sorry, but I can't find anything else. The only explanation on my site was as follows :
>1950? Universal Electric Vehicle Co., Ltd. Electric Vehicle Public Relations Photo
>About this car is completely unknown (please teach those who you know). On the back of the photo is the print of "Universal Electric Vehicle Co., Ltd. Yokohama >City Tsurumi Ward Market Town 588". If you can investigate addresses and company registration documents, you may get some information about universal >electric vehicles. However, this car is similar in overall body design to the above-mentioned Nitta industry Sansei Dan. Unfortunately there are no pictures from >the rear, but from the side view it seems that this is not a three-wheel like San Sedan but four wheels.
Maybe you refer to a catalog ?
