The U.S. Army M5-11-7 Assault Gas Mask was created to be a lightweight combat mask, taking many cues from the successful design of the British Lightweight Anti-Gas Respirator.  It used a modified black M3 faceblank with a 60mm M11 filter canister mounted directly to the cheek, and was carried in a waterproof rubber bag.  The M5 is famous for being the gas mask carried troops storming the beaches of Normandy on D-Day.  This example was made by Daytona Rubber in 1944.
