Gebauer 1934.M GKM

The Gebauer 1934.M GKM was a 7.92x57 mm air-cooled machine gun developed by Ferenc Gebauer at Danuvia in 1934 and was in use from 1934 to 1942 in the Hungarian Air Force.
A revolutionary design for it's time, the 1934.M Gebauer Kényszermeghajtású Motorgéppuska (GKM) was the third of five developments that started in 1918 with the 1918.M. Designed to be used by aircraft as an observer's weapon, the 1934.M used a gas-operated system, with shells ejecting from the left side, and was fed by a 100-round "Horváth" drum, which offered double the capacity of guns used on other aircraft. As time went by it was supplanted by more modern weapons such as the MG-15 & MG-81.
