My uncle came back from germany with a lot of stuff, not all of it lugers and little shiny rocks.
I know a field maintenance group (actually a few members of that outfit) who came home with several interesting things from DS1. I have no idea what happened to it all, but lets just say that huge tool boxes and cases and cases of spares and really big movers and recovery vehicles have lots of space on them.
Also know of a few more modern things, These guys were smarter, as the only seemed to bring back the important little bits.
I too once saw a GI's little basement museum when I was asked to bid on building a bar in his new rec-room. Lets just say, he had all kinds of stuff from Korea. He passed not to long ago, always wondered what happened to all that stuff. He lived in another state, and he wanted me to use katyusha rockets as end caps on his bar, and they still had the wires hanging out the butt end.
