vintage Korean War Era M-1951 Fishtail Parka Shell + Liner RARE US Military

The M-1951 (or M51) military parka is a classic, heavy-duty, three-quarter length overcoat developed by the U.S. Army for the Korean War, famous for its distinctive "fishtail" split hem that could be tied around the legs for warmth, plus a removable fur-lined hood and a button-in liner for maximum cold-weather protection, evolving from earlier models to become a durable garment later adopted by the Mod subculture.
