Colt Paterson Colt Paterson The Colt Paterson is a revolver. It was the first commercial repeating firearm employing a revolving cylinder with multiple chambers aligned with a single, stationary barrel. Its design was patented by Samuel Colt on February 25, 1836, in the United States, France, and England, and it derived its name from being produced in Paterson, New Jersey. Initially this 5-shot revolver was produced in .28 caliber, with a .36 caliber model following a year later. As originally designed and produced, no loading lever was included with the revolver; a user had to disassemble the revolver partially to re-load it.
Colt New Service .455-inch 5.5-inch barrel Mk. I, chambered for the .455 Webley cartridge were acquired for issue as "substitute standard" by the British War Department during World War I. British Empire Colt New Service Revolvers were stamped ""NEW SERVICE .455 ELEY"" on the barrel, to differentiate them from the .45 Colt versions used by the US (and Canada). The Colt New Service was a popular revolver with British officers and many of them had privately purchased their own Colt New Service revolvers in the years prior to World War I as an alternative to the standard-issue Webley Revolver.
