During leisure hours at the front, skilled soldiers created trench art from the remnants of war such as discarded bullets and artillery shell casings. Many of these remnant of war were done with their own equipment and leftover items, but also by items captured and left by enemy soldiers. Trench art objects are holders of soldiers’ memories and reminders of the conflict they faced. Made out of recycled war refuse such as shell casings, spent bullets or whatever came to hand, they open a window to the past. These WWII era FA (Frankford Arsenal) marked bullets are trench art pieces made from remnants of war. DuringWorld War II, the arsenal was again busy with supplying the war efforts, providing a major source of jobs and income for the region. At times, employment reached 22,000. These bullets have been fired and turned into are as each shows amazing craftsmanship with its fluted design.

The M1919 originally fired the .30 cal M1906 (30-06) ball cartridge, and later the .30 caliber M2 ball cartridge, contained in a woven cloth belt, feeding from left to right. A metal M1 link was later adopted, forming a "disintegrating" belt. As a company support weapon, the M1919 required at least a two-man machine gun team. But, in practice, four men were normally involved: the gunner (who fired the gun and when advancing carried the tripod and box of ammunition), the assistant gunner (who helped feed the gun and carried it, and a box of spare parts and tools), and two ammunition carriers.

History of the .50 and .30 cal cartridge during WWII:

Production of small arms ammunition began on March 9, 1942, and the plant remained in production for 42 months. Between 1942 and 1945. The work force reached its peak in July 1943, when employment totaled about 26,000 people, more than half of whom were women. Total World War II production exceeded 4 billion rounds; 2.2 billion rounds of .30 cal and 2 billion rounds of .50 cal cartridges.
