Add an early-war American experimental vehicle to your collection with this detailed model of the T1 HMC (Howitzer Motor Carriage). Developed during the early stages of World War II, the T1 HMC was one of the United States’ initial attempts to mount a 75mm howitzer on a tracked chassis to provide mobile artillery support.
