If you get a chance watch this show. It's Iike American Pickers but just military equipment. Just watched an episode where the guy bought a Panther tank. The whole episode was him trying to determine the history of the tank, find parts, and determine how it was disabled during the war. Most interesting was that he found an intact engine that some guy just happened to have in his garage. It's amazing what is available. Also he fired an a bazooka and a anti tank gun to determine how the damage was done. Very interesting show.
