Firearms expert Jonathan Ferguson, discusses the history and significance of a Smith & Wesson Model 10-11 revolver in this Royal Armouries episode. The Model 10 is described as a well-made, 20th-century double-action .38 caliber revolver, used by military, police, and civilians. The specific revolver discussed was present during the Lockerbie bombing trial held at Camp Zeist from 2000-2002, carried by officers from Dumfries and Galloway Constabulary as a secondary weapon. This particular model, introduced in 1997, is in excellent condition because it was purchased in 1999 specifically for the trial and was out of service by 2003, representing the end of the revolver era in British Police service.
