British Giro Sight Mk II
Here we see the British Gyro Sight Mk II, a gyro gunsight built into a standard reflector sight. The idea was that the pilot would select the correct aircraft on the dial on the gun sight, which is marked with several major German types, from the Bf 109 to the Fw 200. This would select size of the projected circular image (seen top right here with a fighter superimposed). The pilot would use a second control, normally on the throttle, to match the size of the projected image to the actual wingspan of the target. A gyro in the sight measured the movement of the pilot's own aircraft, and a moving target would then be projected on the screen to show the pilot where to aim. The Mk II began to enter service late in 1943 and was the first effective gyro sight to enter service. It was also produced by Sperry in the US.
