Re: Capture papers
The first page is a normal customs declaration; not many returning GIs filled those out and no one bothered them. They were returning on ships by the thousands, not coming in by air a few at a time.
The seond paper is very odd. I have never seen any paper authorizing bring back of Allied weapons under any circumstances, and I can't imagine how a T5 would be authorized to possess them. The gun in question seems to be a German carbine (K.98k?) which is listed under Allied material. Confusing.
