I'm calling this a reenactor special. Original front seam, fixed bale, heat stamp 363B, nice original paint, but has had one bale replaced, and has reproduction chin straps sewn on. The liner is a Mine Safety Appliance (MSA) with original paint and an original painted second lieutenant bar. It has a small crack on the right rear edge, but has all new reproduction webbing, nape strap, sweatband, and leather chin strap.
