Lancaster pistol

The Lancaster pistol was a multi-barrelled handgun made in two-barrel and four-barrel forms in England during the middle and later part of the nineteenth century. It was chambered for several centrefire pistol cartridges, chiefly .38 S&W, .450 Adams, .455 Webley, .476 Enfield and .577 Snider, although most examples were made in .455 Webley and .476 Enfield. It was designed by the London gunsmith Charles William Lancaster, who began his own career in 1847 after the death of his father, Charles Lancaster Senior. Lancaster held a patent for oval bore rifling, a form of rifling with two opposing twisted grooves on each side of the barrel, and he used that system in these pistols.
