This is a very nice example of a U. S. M1917 "Doughboy" helmet, with original liner, that also features original period OD Green paint. The shell is maker marked with a stamping on the underside of the rim that reads ZG 42. The solid rivets and heat lot number indicate that this helmet shell was produced in the United States. The paint is well retained on the shell, though the exterior looks to have been repainted
