This is a plastic model kit, which comes unassembled and unpainted. So glue, model paints and other basic modelling tools are additionally required.
The 37mm M3 anti-tank gun was the first weapon of this type to be manufactured in the United States. But as the US had no experience building such weapons, 2 German 3.7cm PaK 35/36 guns were acquired for evaluation in January 1937. During 1938 several guns and carriages were designed and tested, with the T10 gun with T5 carriage determined the best. These were redesignated as the 37mm M3 anti-tank gun and the first guns were delivered in early 1940. It was the standard anti-tank gun of the US Infantry Divisions and USMC. It was usually towed by a 4x4 1/4 ton Jeep or larger 3/4 ton Dodge truck. The 37mm M3A1 had several modifications including provision for a muzzle brake, and entered service in March 1942. This was the main production model with over 10,000 built. This weapon served in Europe until mid-1943, when it was replaced by a copy of the British 6 Pounder. But in the Pacific the M3A1 served until the end of the war. The M3A1 firing M51 APC ammunition could penetrate 60mm of vertical armour plate at 1000 meters.
