This is an original U. Marine Corps-issued M-1951 Field Parka system, produced under a U. Army contract and later marked for USMC service, a common and documented practice during the mid-1950s.
The outer shell, tagged Regular Small, is constructed from water-repellent treated cotton sateen in Olive Green Shade OG-107, built to MIL-C-11448B (Amendment #1). The contract is dated 31 October 1956 and manufactured by Cohen Fein Company.
Features include the heavy slide-fastener zipper with snap storm flap, adjustable waist and fishtail hem drawcords, oversized cargo pockets, and a detachable button-on hood. Notably, the shell bears a stenciled U. Marine Corps identification on the chest: CREWS F.
/ 1863888 / USMC, indicating Marine Corps issue and individual marking. Included is the correct M-1951 pile liner, tagged Regular Medium, dated October 1955, manufactured by United States Rubber Company, and also marked U. The liner buttons directly into the shell and provides substantial cold-weather insulation. Size note: The parka shell is tagged Regular Small, while the liner is tagged Regular Medium.
This was common in service and does not prevent proper use - the liner buttons in correctly and functions as intended. The liner will fit slightly trimmer inside the shell, which many people actually prefer for layering. Model: M-1951 Field Parka System. Era: Mid-1950s (Korean War / Early Cold War).
