Sorry if everyone got mixed up a bit. The question was "what is this car supposed to be?".
And the answer is : a York Nobel, built in Great Britain, as 75america writes. It's handwritten on the magazine clip (the owner having copied the address in the who appears in a list, on another page of the magazine). See below.
Fuldamobils were built under license in several countries, and I guessed that this WAS indeed a german car (yes guido), because it's LHD and carries a case of Siemens radio. That was the meaning of my clue, as guessed by those two
pros.
