Webley-Fosbery revolver issued to Royal Naval Air Service. Wood plaques are fitted to the butt to form a grip and a lanyard ring is set into the base.The steel solid frame is made in one with the barrel but breaks to load. A large safety catch is fitted to the left side of the top of the grip (down for FIRE and up for SAFE). The cylinder bears deep channels cut into its exterior surface. Unlike a normal revolver, the cylinder of this weapon does not revolve when the action is thumb cocked. To fire, the action is first thumbcocked and the trigger is 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 seven inch barrel is fitted with a pronounced blade foresight and fixed rear sight. The calibre is 0.455in. The serial number '4214' is stamped on the revolver. Stamped on trigger guard is the following: 'A1382'.
