Helmet, M1, 'SP', Anti-Aircraft Artillery

Genuine WWII US Army M1 helmet, front rim seam and swivel loops, manufactured by McCord and bearing shell number 841 A.

Original canvas chinstrap fitted with steel buckle and hook.

Initials SP, which may correspond to mention 'self-propelled', have been painted in white on the front of the shell, while some unidentified, hand-painted anti-aircraft artillery unit insignia adorns its left side.

Quite good overall condition.
