The Webley was a British service revolver in service from 1887-1963. It featured a break top design which allowed the shooter to quickly disassemble the revolver for reloads. It fired the large .455 caliber Webley cartridges, making it one of the most powerful break top revolvers ever made. The official sidearm for the British Military during World War II was the updated Enfield No. 2 Mk I, but due to production shortages the older Webley .455 was also widely used in battle.
