This vintage coat was made in the 1940s, and is an early USN deck coat. It takes its style from earlier sheepskin lined shawl collar box coats, but has an alpaca pile collar and lining, as well as a waterproof layer between the outer canvas and the inner lining. The pockets have leather reinforcements and there are leather loops instead of buttonholes, typical of this style.
