The iconic M1 helmet was first produced by the United States during World War II and was in service up until the 1980s. After World War II many NATO Nations adopted the M1 style helmet and used them actively up until the 1990s. This particular Belgian helmet is made of non-magnetic Hadfield steel. These rare helmets are very close to the original US M1 Helmet and highly collectible. The Thermoplastic liners and suspension appear unused. Steel helmet is in used, nice vintage condition. Genuine European Military Surplus. Limited Quantities!
