Original Items: Only One Lot of 3 Available. This is a fantastic lot of 37mm Dummy rounds, as used with the M3 Anti-Tank Gun. All rounds are clearly marked as being dummy rounds as well as the fuzes. These were never intended to be used as live ammunition and are totally inert, in compliance with the current BATF standards governing ordnance.

Not Available For Export

Target practice shot is for use in target practice and general field practice. The A1 modification does not have a windshield. The projectile is the same as that for the APC, M51, Service Round except that the body and cap of the shot are made in one piece of steel that is not heat treated. The TP M51A2 is similar to the TP M51 and also has a windshield.

All three are in wonderful condition with the expected corrosion and denting in the shell casings. Only one still retains visible blue paint but all three still have very clear markings. They are all marked as being M55A1 and all are dated 1941.

A lovely lot ready for display.

The 37 mm gun M3 is the first dedicated anti-tank gun fielded by United States forces in numbers. Introduced in 1940, it became the standard anti-tank gun of the U.S. infantry with its size enabling it to be pulled by a jeep. However, the continuing improvement of German tanks quickly rendered the 37 mm ineffective and, by 1943, it was being gradually replaced in the European and Mediterranean theaters by the more powerful British-developed 57 mm gun M1. In the Pacific, where the Japanese tank threat was less significant, the M3 remained in service until the end of the war, but some 57mm guns were issued.

Like many other light anti-tank guns, the M3 was widely used in the infantry support role and as an anti-personnel weapon, firing high-explosive and canister rounds.

The M5 and M6 tank mounted variants were used in several models of armored vehicles most notably in the Stuart Light Tank M3/M5, the Lee Medium Tank M3, and Greyhound Light Armored Car M8. In addition, the M3 in its original version was mated to a number of other self-propelled carriages.

The inability of the 37mm round to penetrate the frontal armor of mid-war tanks severely restricted the anti-armor capabilities of units armed with them.
