One vintage red plaid wool hunting coatby Carter's of Lebanon, NH (established 1859).
Red plaid. Thick wool. Doesn't smell.
I guess it's about youth size. Maybe 100# kid max.
Flank zipper pockets. Pair of breast button pockets. Front pockets.
As of today, I still have a pair of adult plaid pants and an adult jacket on ebay.
See my other hunting and mostly archery stuff.
