The Webley Mk VI is a revolver that was used by the British military from 1915 until the late 1960s. It is chambered for the .455 Webley cartridge and features a six-round cylinder. The design is known for its robust construction and reliability, making it a favored sidearm during both World Wars. This revolver was the last in the line of Webley service revolvers, succeeding the earlier models like the Webley Mk IV. Its distinctive top-break mechanism allows for quick reloading, and it has become a popular collector's item due to its historical significance and classic design.
