DEACTIVATED INERT. This is an unfired British Navy 6 inch Mark 5 gun (152 x 1180R) brass cartridge case. The development of the Mark V gun started during the Second World War and was intended for triple Mark 25 mountings on the projected Neptune-class cruisers. In 1946, the gun was redesigned to be mounted in pairs to the new and complex Mark 26 dual purpose mounting and gun turret designed for rapid automatic fire on the projected Minotaur-class cruiser. These were to be the first British 6-inch guns in over sixty years to use brass cartridges instead of bagged charges. By the time the first two experimental weapons had been completed in 1949, the Minotaur-class had also been cancelled. The N5 gun was used in the Mark 26 mounting, on the Tiger-class cruisers, whose hulls had been built during the war and had since been totally redesigned. The Tiger class ships (comprising HMS Tiger, Lion and Blake) and were commissioned in 1959 but the weapon systems proved unreliable in use. With changes in use and requirements with the Royal Navy, the ships were finally decommissioned in 1979. The ships carried two twin 6-inch mark 5 guns in mounts, fore and aft, and together with the ships' 3-inch guns. This brass unfired rimmed straight cartridge case measures 1180mm in length and is headstamped 6 INCH MK N5 GUN NI over a crowfoot and RLB (ROYAL LABORATORIES). The base is also stencilled in black with the filling data RNP N2 2588 34LB 8OZ GD 5/ 60. The base is screwed for a screw in primer. The case mouth has brass screw thread rolled into it to hold a protective charge cap. The price of this rare round includes UK delivery and no licence is required to possess inert rounds in the UK if retained as a part of a collection or display. (No34). O 1836
