Which famous aircraft producer designed the synchronized machine gun to fire through propeller blades?
Machine gun Nieuport 11 which avoided the propeller entirely, or armored propeller blades such as those mounted on the Morane-Saulnier L which would allow the propeller to deflect unsynchronized gunfire. By mid 1915, the introduction of a reliable gun synchronizer by the Imperial German Flying Corps made it possible to fire a closed-bolt machine gun forward through a spinning propeller by timing the firing of the gun to miss the blades. The Allies had no equivalent system until 1916 and their aircraft suffered badly as a result, a period known as the Fokker Scourge, after the Fokker Eindecker, the first German plane
M1919 Browning machine gun could be used in flexible- (pintle-mounted), fixed- (wing-mounted), or synchronized- (through the propeller) models. The Flexible mount machine gun came with grips and a "butterfly" trigger plate like the standard ground model. The Fixed model had a backplate. It used a cable connected to an operating slide connected to a stud on the bolt to fire it; tension in the cable causes the trigger to activate and slack in the cable causes it to stop. The synchronized variant of the Fixed model had a trigger motor for through-propeller, gun synchronizing needs. The Browning M1919 remains popular with civilian enthusiasts in
