[Milsurplus] What is it? Clandestine?

>Could the radio be a war trophy, brought home by someone, then offered for sale after the person died or lost interest in it? What were the regulations after WW2 regarding bringing German and Japanese radio gear home? 

I think that's undoubtedly it. As I understand it, by reading some rules documents, during the war, you were quite limited as to souvenirs - generally it was uniform items.
Not any kind of "scientific item". Rules got bent. I don't know if you could mail back packages during the war - letters were reduced to microfilm for transmission. 
When at end of war, you could send packages back, you had to - as I understand it - get a release form, that the items were permitted souvenirs. I'd say within a year that
was history and whatever could legally go thru mail, could be sent. Some vet could have picked up the item, either during the war or picked it up afterward, when dollars
were king, then sent or carried it back.
