Perhaps the web site operator has more information.

::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

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.

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.
