This is an original WWII U.S. M1936 musette bag, commonly utilized by paratroopers and officers. It was manufactured in 1942 by Atlantic Products Corp. Twice-stamped near the manufacturer's marking is the original owner's laundry number, "F-4733". It appears to have once been anti-gas impregnated, as it has become somewhat stiff. Unfortunately, one of the front straps is missing its brass end-keeper. This musette bag would display quite nicely when completed with a belt and suspenders.
