This vintage jacket was made by Monarch Mfg. of Milwaukee WI in the late 1930s or early 1940s. It is a belted, double breasted style. This has since come to be known among collectors as a barnstormer style, named after the aviators of the 1920s who wore similar styles. The jacket is made of russet horsehide, with a 3×6 double breasted front. There are handwarmer pockets (known originally as “muff” pockets), as well as flapped cargo pockets. These have deeply scalloped pocket flaps. The jacket is lined with blanket wool in the body, with quilted shoulders and sleeves. The U shaped seam between the two lining materials is a detail I have only seen on other Monarch jackets. The label is of a style used in the 1930s through about the end of WWII. The leather has some really incredible grain, highlighted by decades of usage. The treatment of the seams is unusual. Whereas most jackets, leather or otherwise, will have a seam at the edge of the jacket, or on the edge of the lapels, this one minimizes them by folding the leather around to form the front and back panel.

The Monarch Manufacturing Company was founded in 1892 by Paul Asch. In 1917, they relocated to a new factory, located at 246 East Chicago St., Milwaukee, WI. They built at least four more factories in Milwaukee, employing over a thousand workers by 1922. Throughout the life of the company, they specialized in leather, sheepskin and fabric outerwear for men and boys. They produced A-2 contracts during WWII.
