This is a Japanese 7.7 x 58 mm gas-operated machine gun that consists of two paired Type 11 machine guns referred to as the “Flexible Type”. The modified Type 11 barrels of this gun had no cooling fins and a breech loader with tube fixed to the housing. Characteristic for this Dual Type 89 is the Y-shaped ammunition supply with spade grips on top of the gun consisting of two attachable compartment magazines that housed 90 cartridges each.
During World War Two the Dual Type 89 was commonly used as a tail gun on various Imperial Japanese Air Force aircraft like the Mitsubishi Ki-21, Ki-67 and Nakajima Ki-49 heavy bombers, the Mitsubishi Ki-30, Ki-51 and Kawasaki Ki-32 light bombers.
The machine gun was also used on the ground for assault and anti-aircraft purposes.
