WWII RAF Air Gunner's Prismatic Gun Sight Type G
An Early 1939/40 RAF Type G, Prismatic Gun Sight.
Produced by RAE as an alternative to the Reflector Gun Sight, this small optical sight was produced in two variants, the type A for pilot's and the B for gun turrets.
This Gunsight proved difficult to use due to its small size in particular the small eye piece. As a result all production on prismatic gun sights ceased later in 1940.
This type B sight would have been produced with the Boulton & Paul Defiant gun turret, in mind which was used on several aircraft
This example is in good condition with a moveable sunscreen
