This vintage coat was made by the A&N Trading Co of 8th and D St. NW Washington DC in the 1930s, either for the Army or the Civilian Conservation Corps.  It is the rare early variant of the army shawl collar mackinaw, made from OD wool, with a double breasted closure, belted waist, and epaulettes.  In keeping with the early pattern, and typical of work mackinaws of this period, the coat is unlined.
