This is an original WWII U.S. Schlueter manufactured swivel loop M1 helmet shell. It was used by the commanding officer of a naval vessal. The heat stamp of 312A dates the helmet's production to late-1944. It retains its original battleship grey paint, cork texture, and slightly damaged chinstraps. Whether the new owner decides to complete the helmet with a well used late-war liner or restore it with an intact chinstrap, this helmet will make an excellent display piece.
