1937 Pattern Khaki Web Belt with regular and double width keepers. The 1937 Pattern Web Equipment (also known as '37 Webbing') was an item of military load-carrying equipment. It replaced the 1908 Pattern and 1925 Pattern—on which it was based—and was standard issue for British and Commonwealth troops from its introduction in 1937, throughout World War II, and in the post-war period until it was superseded by 1958 pattern webbing.
