Vintage 50s Korea US Army M-1951 Fishtail Parka Shell Jacket Size Small

This coat is in great condition, the only flaws are a few small stains/holes all flaws are as seen in the photos. Dated 1953 or 1958 it’s hard to make out for me, I’m more so leaning on the date being 1953 but you be the judge. Measurements: Pit to pit-26” Length-39” Shoulder width-22.5” Sleeve length-24.5”
