A little background. The LMG Model MG 14/17 machine gun was a 7.92mm gun used on aircraft and Zeppelin in WWI. The 17 designation means that the gun was the 1917 version of this particular weapon. MG-14/17's were used very widely on German multi-seat aircraft throughout 1917 and 1918, particularly as the weapon for the rear gunner/observer on two seat planes.
Eduard has produced a resin and photoetch replacement for kit parts representing this gun. Inside the package, you get parts for two guns. The resin parts consist of the stock, the gun itself, the ammo drum and the sight. The photoetch parts consist of the gun sight, handle, the sides of the ammo drum, the supports for the gun sight and the trigger assembly.
