|Now you can order an American-made 1945 M37 tank with a 105mm Howitzer mortar cannon from a auction(July 12, 2014).
"The vehicle being offered, M37 105mm HMC, serial number 115, was built in October 1945 by American Car and Foundry. It was used as a training vehicle at Fort Knox until the mid-1950's after which time it was sent to Sioux City, IA for display. It was sold for scrap in 1989 in very poor condition. A complete and thorough restoration of the M37 took place at the MVTF during 1994-95 with many parts being rebuilt or replaced. This M37 is beyond a doubt the best one in existence! Included with it are a full load 105mm howitzer round packing tubes. It was last driven in January 2014. "
