Webley Fosbery revolver. The stock consists of walnut plaques fitted to a steel butt to form a grip with a lanyard ring set into the base. There is a solid frame made in one with the barrel but 'breaking' to load. A safety catch is fitted to the left side of the top of the grip (down for FIRE and up for SAFE). The cylinder instead of being the normal Webley pattern bears deep channels cut into its exterior surface. Unlike the normal revolver, the cylinder of this weapon does not revolve when the action is thumb cocked. To fire, the action is first thumb cocked and the trigger squeezed. If fired straight armed (and no other course is really possible) then the entire upper half of the frame recoils along the top of the lower frame. The cylinder has six chambers. The barrel is six-sided externally with a pronounced blade foresight. The calibre is 0.455in. The top of the barrel is inscribed 'P WEBLEY & SON, LONDON AND BIRMINGHAM'. The top of the frame is inscribed 'WEBLEY FOSBERY', on the left side lower frame is '455 CORDITE' and on the right side lower frame '3548' (which is the serial number). Each chamber bears a proof mark as does the barrel, a crown over 'BP'.
