This guide details the unique gas-operated, swinging lever mechanism of the Marlin Model 1917 Machine Gun, a licensed Colt design. Expert Ian McCollum explains how gas pressure from a port under the barrel actuates a lever connected to the operating slide, cycling the action. The nickname 'Potato Digger' is attributed to the lever's violent motion.
The Marlin Model 1917 (7MG) is a WWI aircraft machine gun based on John Browning's Model 1895, redesigned by Carl Gustaf Swebilius for aircraft use. It features a straight-acting gas piston, a tilting bolt, and a unique synchronizer mount for firing through propellers. Early models had extraction issues resolved by adding weight to the gas piston. Its belts have distinct cartridge spacing, making them non-interchangeable with later designs.
