History
The British 6 Pounder Anti-Tank gun was manufactured in the US, in 1942. In early 1943, the US Army adopted it for their use and called it the 57mm Anti-Tank gun M1. The version adopted for the army was modified and supplied to the army with a modified towing hitch and “Combat” wheels. Most branches of the US Army considered the weapon as too heavy and it was also hampered by the lack of ammunition. In 1943 only simple armor piercing ammo was manufactured. It wasn’t until late 1944 before adequate AP ammunition was made available. The M1 could penetrate 75mm of armor angled at 30 degrees at a distance of 3000 meters. In spite of the shortcomings, by early 1944 the M1 had become the standard towed anti-tank gun of the US Army Divisions. The prime mover for the M1 57mm was the Dodge WC-63 and the White halftrack. Over 10,000 M1’s were built for the US Army and 4,242 for the British Army. The M1 was also used by the Free French and Russian armies.
