USAF Korean War Era 1950's Chief Master and similar items

This garment came through the battles and the years in very good condition with nothing you would call damage, no worse than a tiny blemish anywhere and you have to look close to find them. As nice as practically expected for what is possibly if not likely a combat worn item. Made in 1952 to a 1946 pattern so works for reenactments of multiple types. You have to look closely at the last two photos but they show the faint outlines of patches that were present, triangle above and chevrons below, looks like space for two of them. Chest 40" at the armpits, 36" bottom of ribs and 38" at the waist so slightly fitted. Sleeves 24" from the top of the shoulder and 20 1/2" about from the armpit. So I suppose it is a medium but if you want to wear it go by the measurements please. It IS worth wearing, they do not make them of this quality today, nice material. Yes I sound like a rag district barker what do you expect ha ha?
