The 9mm Browning Long was designed by the famous John M. Browning for FN in Belgium in 1902 and was first adopted in 1903 for the Browning M.1903. it is basically a scaled-up version of the 7.65mm Browning and also retains the semi-rim. It should have been a very successful design, but the introduction of the 9mm Parabellum at the same time made the Browning Long doomed from the start. (Erlmeier, Brandt Ref. 116).
