Ken, either the Germans missed a bunch or else reproof was uncommon on the ones they confiscated. Quite a few French doubles floating around in this country, reported to have been war souvenirs collected by the GI's, without reproof. Matter of fact, I'd say a French gun with a German reproof is a pretty rare critter.

I often wondered whether the first classic sxs I ever owned--pre-WWII Sauer 16--might not have been brought home by a GI. None of the standard indications of a gun having been made for export. So probably a good chance it came home in someone's dufflebag, or else maybe was purchased by a GI in Germany at some point after the war.
