This vintage canvas hunting jacket was made in the 1920s by Duxbak. It is their early style of hunting coat, introduced in the first decade of the 20th century, with double hip pockets, and a double breast pocket. For both, the double pockets share a single flap. This jacket has the early version of what would later become the “half-moon” pocket, a pass through on the front of the coat to the interior game pocket. The jacket is a double thickness. The pockets have been lined/patched with selvedge salt and pepper cotton. Underarms are double-panel gusseted and have ventilation grommets. There is a calendar in the pocket dated 1939, presumably the last time this coat was worn in earnest. With the amount of wear put on it, its safe to say it dates from some time before that. The style of label and style of the coat confirm a 1920s date of manufacture.
