This vintage jacket was made in the 1930s by the Hettrick Mfg. Co of Toledo Ohio under their American Field Gun Coats label. Hettrick was a producer of a variety of canvas goods. This is the earliest label I have seen. The coat has shotgun shell pockets, large cargo pockets, a double breast pocket, game pouch and gusseted arms. It has a corduroy collar and cuffs.
