Vintage 50's Korean War men's M/L tan khaki wool long sleeve military shirt

Vintage early 1950's 50's Korean War men's M/L tan khaki golden wool long sleeve military shirt! see measurements as I am unsure of size. He was a marine in the Korean War. Buttons up the front with collar. Two front buttoned pockets. Sleeve ends button. This one doesn't have any military patches anymore. All original buttons intact. There is a couple dark marks around (see photos). Does smell old and will probably need a clean. Happy to answer any questions :) Measurements: Pit to pit - 21 1/2 inches across. Length from shoulder to hem - 29 1/2 inches. An inch longer in back. Shoulder seam to shoulder seam - 16 1/2 inches across. Sleeve length from shoulder seam - 23 inches. Sleeve length from armpit - 19 1/2 inches.
