The Webley-Fosbery is one of the most unusual firearms ever produced — a self-cocking revolver that uses recoil to automatically rotate the cylinder and cock the hammer, combining revolver and semi-automatic operating principles. Designed by Lieutenant Colonel George Vincent Fosbery and produced by Webley & Scott, it was used by British officers in WWI for its precise single-action trigger. Featured in The Maltese Falcon as the "most unusual revolver" in the world.
