From about 1854 to 1879 William Moore and William Grey manufactured fine firearms from their 43 Old Bond St. London address under the name William Moore & Grey. It is likely that this rifle was built during the transition to the Moore/Grey partnership as the barrel is marked with the "WILLIAM MOORE & Co" trade name and the Old Bond St. address as well as the bolster featuring an early platinum lined vent hole while the lock is marked with the "Wm MOORE & GREY" trade name. The Damascus barrel is fitted with blade front and folding ladder rear sights, the lock has a sliding safety, and the trigger guard tang forms a semi-pistol grip. The stock has a shadow line cheek piece and is checkered on the forearm and wrist in the volunteer style.
