US Model 1917 "Doughboy" helmet, based upon the British "Brodie" pattern [ca. 1918-1919]. Steel shell with leather, oil cloth and string liner with felt pad, absent the canvas/leather chinstrap.

The primary insignia features a finely hand-painted red Corps of Engineers Castle insignia nestled inside a cream-colored geometric shard. Adjacent this symbol are three gold overseas service chevrons and "504 Bn." The interior features the heat code "ZC177" and pained initials "S.L."

The US 504th Engineer Battalion was deployed to France in late 1917 as part of the American Expeditionary Force (AEF) and provided infrastructure support in both the rear echelon and front lines, doing everything from maintaining roads, bridges and railways to help keep supplies and troops moving, to running supply depots and assisting with logistical operations. After the war the battalion was involved with some of the battlefield clean up. They returned to the US in 1919.

A visually spectacular combat heirloom from the AEF of World War I. This steel helmet serves as an exceptional canvas of trench artistry, completely covered in irregular "cubist" lozenges of camouflage paint with black separating lines worked in three hues of green, ocher brown and maize yellow. Far more than a generic camo helmet, this piece is heavily adorned with specific unit insignia and personal identification.

The helmet is in good to very good condition. The exterior painted surface is well-preserved, with the hand-painted camouflage showing minor, expected wear. The internal liner is remarkably intact, with the black oilcloth liner band and internal protective netting remaining strong and flexible.
