This is an original American Civil Defense helmet from the World War II era. It was produced on the basis of the M1917A1 steel helmet (“Kelly helmet”) and painted in a characteristic light shade. On the front, it bears a large colorful decal of the U.S. Office of Civilian Defense insignia – a blue circle with a white triangle and a red shield in the center.

Inside, the original markings are preserved: “PROPERTY OF U.S. GOVERNMENT O.C.D.” along with a serial number. The liner is made of textile webbing with leather reinforcements and an adjustable suspension system. The photographs show the typical paint darkening, signs of age, and surface wear, which add historical authenticity to the piece.

These helmets were used by U.S. Civil Defense personnel – including firefighters, rescue workers, medical staff, and police units – responsible for civilian protection during air raid alerts and drills in the 1940s.
