M1916 37mm gun

The M1916 37mm gun was developed by the French and used primarily by French and American forces in WWI for destroying machine gun emplacements. It was fairly good at this under fluid, mobile conditions, but inferior to mortars for static trench warfare. It was still in limited service by World War II, but generally relegated to training and use as a sub-caliber addition for larger guns.

Ammunition was of two types initially, a 1-pound solid steel shell and a high explosive round. The solid round was found to be largely ineffective, and replaced with a bursting shell of cast iron and filled with black powder. Mounting for the gun was either a fixed tripod or wheeled carriage.

Mechanically, the M1916 used a rotating breechblock and hydraulic recoil absorber coupled with a spring recuperator. In addition to use as an infantry gun, the M1916 was also mounted in the early US M1917 Renault tank.

      I’m looking to learn more about the 37mm gun model of 1916 empty shell casing I have. It is 2.95″ to the neck down angle, 3.61″ overall. Head stamp AML01090-44-B 4114-33 WPS Co. Was this used as an anti tank catridge? Seems to small to me. Thanks for any help. RJ

  • I have a related question concerning the 37 mm semi-automatic M1924 gun; this was allegedly fitted to the T1E4 version of the experimental US T1 Cunningham tank of the 1920s.

    Does anyone know more about this?

  • Having done some more digging, I can partly answer my own question: the M1924 was a Browning design using a long-recoil action. It used a unique 37 x 124R round.
