Army helmet WW1

Original, battle worn World War I German army helmet no liner has bullet entry hole in the rear, and bullet exit hole in front. The rest is only surface rust and the helmet is not fragile in any way. There are signs of some personalization and customization on the outer shell of the helmet there are remnants of paint that are visible in shades of green and brown. The helmet is an M16 model size ET64 (the stamp is still visible on the inside of the helmet) this particular piece of memorabilia tells an interesting story it's very rare to have a helmet with still visible traces of custom camo painted by the soldier and a bullet hole in the back of a helmet and especially rare occurrence during World war 1 because of face to face trench fighting.
