Gyro Gunsight Mk 4E
The RCAF gyro gunsight mostly used post WWII, was the GGSMk4E, which was fitted to many post-war fighters (apart from night-fighters, which continued to use the GMII). The need for a protective rubber buffer had brought about a redesign which resulted in the Mk4E having its span dial inverted. Also, the lever that raised and lowered the tinted filter glass was moved to the left hand side of the sight and the mechanism improved so that the filter glass would lie flush against the sight top.
Note the span dial now has an RP setting - this would be the position used for aiming at ground targets with Rocket Projectiles.
