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

Here we have a true vintage M-1951 US Army fishtail parka shell complete with the liner inside still too. Even if it wasn't a harder to find sought after old military item, it's still functional and wearable right now and about the warmest, super comfortable and roomy coat you could imagine if you want premium vintage for use. So this has all the printed info clearly legible on the interior of the hood, I can't find a printed or tagged size on the parka, but the liner has a printed size of small. I find that odd because the shell parka measures 30 inches across the pits, and the liner itself measures 25 inches, so it seems to me like it fits more like a 46-48 type range?

IDK but that's the info I see compared against how it measures, more measurements given below too so check it out below here. Zip works great, all buttons, straps, and drawstrings present with the leather tabs present.

It has some spotting/staining here and there throughout but not terrible, see pics. On front it has some kind of white marks, maybe some paint/drywall or something like that? Also more faint marks on the body and around the sleeves/cuffs area, the sleeves/cuffs also have some other wear/tiny hoes, but no actual holes visible or present on the body of the fabric torso, so nothing really obvious or plainly visible. Overall really solid wearable shape with all functions still in proper order. Pit to Pit: shell 30 / liner 25.
