11mm Vickers "Balloon Buster" Machine Gun
The 11mm Vickers 'Balloon Buster' was a specialized WWI aircraft machine gun designed to ignite hydrogen observation balloons with incendiary rounds. Modifications included an air-cooled jacket and a remote fusee spring adjustment system. It also featured a Birkigt synchronization gear for firing through propeller arcs and mechanical reinforcements to handle the heavier recoil of the 11mm Gras cartridge.
