A breech loading 2.75 inch mountain gun of the 5th (Bombay) Mountain Battery, 1933

Photograph, India, North West Frontier, 1933.

The 2.75 inch Mountain Gun was primarily used by the Indian Mountain Artillery on the North West Frontier during the inter-war period, although some were also used during the Mesopotamia campaign in World War One. The 2.75 inch was a screw gun design, where the barrel could be separated into two parts via a screw joint. This allowed the gun to have a heavier barrel, but still be broken into smaller portions for transport by mule teams. This was important for a weapon designed to be used in mountainous terrain.
