The National Military History Center in Auburn, Indiana is auctioning off part of their collection in order to settle their mortgage. Auctions America is handling the auction for them. The auction catalog is here.
They will be offering 100 lots of WWII artifacts and 82 lots of military vehicles.
Worried about Predator drones flying overhead? Then how about an 88mm flak gun - demilled unfortunately?
Tired of having to fight traffic? How about this - a 1944 M16 half-track with double M-2s in a motorized mount?
You say you like that idea but want German engineering? How about this 1940-41 Hanomag S.P.W. Ausf. C SdKfz 251/1 Armored 3/4-Track?
I didn't see any tanks in the catalog but there are a lot of motorcycles, trucks, and other assorted vehicles along with the uniforms and demilled MP-40 sub-machine guns. None of these auctions have reserves but I expect collectors will be paying a fair price for some of these items.
