Browning and FN Herstal now began to work closely together, with FN Herstal producing an initial order of 10,000 shotguns. These were sold by Browning within a year, leading Remington to pick up on the design as well. Nevertheless, Browning's closest ties where with FN Herstal, and by 1907 Browning had agreed to allow the Belgian company to manufacture arms using his name. Among the arms produced by the FN Herstal-Browning team in this period were a 9mm military semi-automatic pistol in 1903; a pocket-sized .25 caliber semi-automatic in 1905, and a semi-automatic .22 caliber rifle in 1914. In that year, Browning received the Order of the Knighthood from the Belgian throne in recognition of his contribution to the Belgian company's growing worldwide reputation. The company received more dubious distinction as the maker of the automatic handgun used in the assassination of Archduke Ferdinand, setting off World War I.
