Hi CHrister
Well, given that it is a pocket radio and more than likely a transistor radio, it could date from the late 50's to the late 70's, thats about the best guess I can make, hope this helps you.

Well the radio is really a pocket radio but supported with three radiotubes 1S5,1R5,1T4 and one 45 voltage and one 1,5 voltage battery

Hi Christer
Well, if it has tubes in it then it would be of the 50's vintage, very interesting, would be neat if you could send a photo of it too me, my E Mail is electro276@cox.net

Christer, do you mean "portable radio" as opposed to one that would fit in you shirt pocket?

From way back in my memory, it seems I remember trying to repair one of those sometime in the fifties. It was more or less like the portable radios of the day, only it had only the 1.5 Volt tubes, and no audio output tube, as it only powered an earphone. It was a superhet radio, small enough to fit in a pocket, as it had no speaker. It seems the one someone gave me to fix was badly corroded from battery leakage, and was not repairable. You might look a a schematic for a regular battery portable from about 1955, it should have more or less the same insides as yours, or at least enough for you to get started. Let us know what happens.

At this point i have come to the conclusion that the radio was made in Japan about 1954-56.
But still there is a mystery about the radio company!
did they only produced this small radio and then disaperaed or changed the name?

Christer, go here: http://www.transistor.org/tubes/noveldempa.html

This all I could find out about your radio, but this is a very interesting site, she and her husband have trains, airplanes, radios, and a lot of other stuff. I enjoyed it, and I think you (and the others) might just like it, too.
