History

The Breda Model 31 was a license built copy of the French Hotchkiss M1929[3] machine gun. Breda acquired a production license in 1929, but it did not enter production until 1931. The Model 31 was often mounted on single and twin mounts aboard surface ships and on a disappearing twin mount aboard submarines.[4] The Model 31 was intended to provide close-range air defense, but like its counterparts in other nations, these small-caliber guns were found incapable of defending against low-level torpedo-bombers or high altitude level-bomber attacks because their bullets were too light and short ranged.[5] Although a reliable gun with good performance, it was later replaced by the Breda 20/65 Mod. 1935.

Construction

The Model 31 was a gas-operated, air-cooled machine gun with a tilting bolt action. It was fed by top mounted, semi-circular, thirty round magazines, with cooling air drawn through the sleeve to fins along the barrel.[6]
