This piston played a critical role in the breech mechanism of the M41 gun, helping to cycle and close the breech after the firing of a round. It ensured reliable loading and firing—vital to tank crews during both training and combat situations.
The M41 90mm gun served as the primary armament for the M48 Patton series, which became the backbone of U.S. and NATO armored forces during the 1950s and 1960s. The M48 saw extensive service in Korea, Vietnam, and with numerous allied nations worldwide. The robust M41 gun offered effective armor-piercing capability and was respected for its accuracy and recoil management.
This breech spring piston may also have been used in earlier 90mm gun variants such as the M36, mounted on the M47 Patton, further increasing its historical and collectible significance. Both the M47 and M48 represented a technological evolution from WWII tank designs to modern armored warfare.
