WW2 US M1 Helmet Rear Seam Swivel Bale With Liner

The WW2 US M1 Helmet Rear Seam Swivel Bale With Liner is a standard-issue combat helmet used by United States military forces during the Second World War. This version features a rear seam on the steel shell, a manufacturing change implemented in late 1943 to streamline production. The swivel bale design incorporates moveable chinstrap loops, allowing for increased durability and flexibility compared to earlier fixed bale models. The included liner, typically constructed from compressed fiber or plastic materials, provided the wearer with added comfort and better fit retention. The M1 helmet was widely employed by the US Army, Marine Corps, and other branches, becoming an iconic piece of military equipment. This artifact is valued for its representative construction details, such as the stamped steel shell, olive drab paint finish, and adjustable suspension. The rear seam, swivel bale configuration marks it as characteristic of mid-to-late WWII production.
