WWII US M-1 Helmet with EARLY Hawley Liner-Super desirable! The shell is excellent, with 99% of the finish intact. It is a front seam, fixed bale example with OD 4 chinstrap and brass hardware. I cannot read the heat stamp number. The Hawley liner is excellent. It has none of the typical breaks of soft spots that are found on many of these paper based liners. It is a very early example with rayon suspension, unfinished rectangular washers and fixed brown leather chinstrap that is unbroken. A simply awesome set!
