Type 92 machine gun

The Type 92 7.7mm machine gun (九二式七粍七機銃)　was developed for aerial use for the Imperial Japanese Navy before World War II. It was the standard hand-held machine gun in multi-place IJN aircraft during the most part of the Pacific War. It proved to be seriously inadequate. Aircraft produced in the later part of the conflict often were eqipped with weapons such as Type 1 and Type 2 machine guns or Type 99 cannon.

Basically a copy of the ubiquitous Lewis gun, the Type 92 was fed with a drum magazine and used in a flexible mount. The main external difference between the two models was the latter's lack of casing and cooling fins around the barrel and gas piston tube, as well as the most noted trigger guard.
