WW1 M18'ear-cut-out' camouflage steel helmet ET64

Very desirable M18 ear-cut-out steel helmet. Shell only, used as a grave maker for a KIA soldier. Helmet was camouflaged in two tone colors, flaking off, exposing the factory green finish underneath. Barn-found condition – dusty and rusty but very rare! ET was the only manufacturer for these helmets, they are always marked ET64, due to the rust and camo paint, the markings are not visible anymore.
