Original U.S. WWII Officer M1911 Campaign Hat - Army Model

The Hat, Service, M1911 (Campaign Hat) was made of OD wool felt with a wide brim and "Montana peak" crown. There were ventilation holes in the crown with grommets, a silk hatband, and a silk and brass braid cord closed by a knot and terminated with a tassel. Inside was a leather sweatband and an attached chin strap. The Army model was dark brown OD in color.

The hat cords were worn around the base of the crown indicated the branch for enlisted men and rank for officers. The system was similar to the piping colors for the Garrison Cap, copied from the Campaign Hat. Unit and rank insignia were sometimes worn on the front of the hat when authorized.
