For the ultimate in WWII firearms art, consider the all glass Type 99 LMG from Mickelsen Studios. This work of art is made of borosilicate glass using a process called lampworking. Borosilicate glass tends to be a harder glass that other forms that are used in lampworking.
This work is 51″ long (about 1.3 meters) and appears to be a fairly close replica of the original WWII machine gun.
During World War II, the Imperial Japanese Army used the 7.7x58mm Arisaka as a light machine gun. The glass version from Mickelsen Studios features a forward bipod and an attached bayonet. The buttstock monopod seen on some Type 99 LMGs is not replicated.
