Notes:

After WWII a new generation of jet fighters such as the Gloster Meteor and de Havilland Vampire saw the development of new marks of the Gyro Gunsight. The Mk5 GGS Mks 4B/C and Mk5 were examples of these improved Sights. They were made by Ferranti at Crewe Toll near Edinburgh and there was a licence to Sadir Carpentier (later CSF) to make them in France for the Mirage. Later variants introduced electrical control of the range. More sophisticated radars were being developed with greater capability than radar ranging. The search and track mode really benefited from a head-up presentation. In the Gloster Javelin all weather fighter the BPGS was a system which combined the Mark 7 GGS with a collimated Cathode Ray Tube for presenting a search radar picture which was presented with the normal GGS presentation. The pilot could track the spot on the CRT with the centre spot of the six-diamond pattern of the GGS although in practice this proved difficult. The Mk8 system fitted to the Hunter FGA Mk9 and had a number of inputs from the aircraft systems such as the throttle, altitude and ballistics as well as the radar. This system also had limited air to ground computation and a similar combined display but with a brighter CRT.

This Gyro Gunsight is on a presentation base and is a demonstration unit without any markings. It is most similar to the Mk4E design.

The given dimensions are for overall. The smaller base depth is 221mm and the gunsight itself is:
160(W) x 180(H) x 282(D) mm.
