Front seam, swivel bale McCord M1 helmet with stenciled black 7. Looks to be the original OD paint. No way to prove this but given the characteristics of the dents on top of the helmet it’s not too much of a stretch to consider they may be combat battle damage. The liner is a WWII Firestone with khaki webbing and an OD7 green suspension drawstring (most likely not original to the liner). Shipped USPS ground Advantage.
