This original WWII U.S. Schlueter manufactured swivel loop M1 helmet shell is in excellent condition. The heat stamp of 557A dates the helmet's production to 1945. It retains its original factory paint, cork texture, and OD#7 (green) chinstrap. Interestingly, this helmet's chinstrap features a relatively early J-hook, whereas this example, with a lower heat stamp, has a T1 style buckle. This helmet would pair very nicely with a high pressure helmet liner with blackened brass A-washers.
