Can't say on the serial numbers, but I do have a papered Dutch contract 1922 that was captured by the Germans apparently, and issued to a Luft pilot...it was captured in a Luft drop holster, and was captured directly and taken from the pilot by the father of a friend of my Moms, I got it directly from the footlocker in the attic from the son (kooky liberal sort didn't want any guns in the house, found it in the attic after his dad passed...)
So I can say for sure that one went to the Luft...
