Im a collector (not exactly this kind of stuff-yet) but-always keep everything associated with it. I bought a .22 cal STG-44 knockoff a few years ago-it was a crated rifle-which also came in a crate-size cardboard box. I also kept all the doodads etc that was inside the box-even plastic. If I ever sold it many years from now-it would be one of the raer pieces that is complete-originlal reciept and all.

About 8 years ago-on a militaria dealers site I used to buy from-they had a WWII German Mauser 98 box of ammo made of thick cardboard with metal suppports on all the edges with makers info yadda yadda. It was the same size as the metal cans-but this was for rifles only-and inside this cardboard box, were cardboard boxes that held 20 rounds each. I think 300? rounds total came in this. Some idiot who had it before-opened the outer box, then opened one of the inner boxes-I guess to see wat condition this stuff was in. It looked like it was just made it was so good. Each round of the opened box-date and maker-stamped and had a Waffenamt (small German eagle w/swaz underneath)on each round. This box sold ver quick at $1,500. I wanted it badly-but couldnt force myself to pay that price. I bought a near mint pair of Generalmajors shoulderboards instead-to go with my Generals collartabs.

BTW, last year I also bought the MP-40 knockoff as well. I was a bit perturbed they threw away the outer box for that crated rifle. Everything else is still with it though.
