Vintage M-1951 M-51 US Army Korean War Era 1953 Dated Field Coat Jacket S/M

Great original Korean War M-1951 M-51 US Army field jacket. No neck labels but printed specs inside right side.

Bottom snap has pulled out but still present. Some staining on sleeve and on side near pocket but the stains don't take away from the jacket. Check measurements but seems to fit like a loose Small or regular Medium.
