So this really is an intriguing (and for the moment unique) transistor radio for the collectors out there with plenty of scope for research. When Toshiba entered the Transistor radio market in 1957 they did so with gusto producing a score of beautiful, iconic and sometimes bizarre radios. This is clearly one of the latter group!
Most of the early Toshiba radio models have now been well documented, but despite endless searches I have yet to find any mention of this particular model anywhere (even in Japanese) . My thanks go to Eric Wrobbel who I also consulted, and again he had never heard of or seen anything like it before either. The dial numbers suggest it was intended for the US market probably as a pocket-sized desk top radio, but the plain and unusual shape is also reminiscent of models intended for use on a Car dashboard (but this has no mounting points so would slip around if so). Interestingly the three divots on the top suggest it may also have been designed for something to rest on top of it, but again this is all just speculation. All we do know is that the model number is very unusual and although it is clearly an official Toshiba product, still has some very hand constructed elements (such as the screws that hold the name plate on and the somewhat flimsy battery flap).
So this really is a fascinating and for now mystery Toshiba……….your thoughts??!
