The Westley Richards Droplock Double Rifle in 500/465 NE was produced in the brief window between the 1907 ban on 450-caliber cartridges and the 470 NE's consolidation of the market. Chambered in this transitional cartridge, these guns are historically significant as examples of the rapid market evolution that followed the colonial ban, and as among the earliest dangerous-game Droplocks produced.
