RAF Reflector Gunsight Bulb

The Reflector Gunsight used a frosted, half-silvered bulb which lit up the aiming pattern at the bottom of the body of the sight. The bulbs were either 12 volt or 24 volt, depending on the aircraft and could have been used on late mark Spitfires, Typhoons or other fighter aircraft with a 24V system. The Reflector Gunsight Mk II was the mainstay of the RAF fighter from 1941 until the Mk IID Ferranti Gyro gunsights began to enter service in 1944;the advantage of this model was it would automatically compensate for the movement of the aiming aircraft. We have a small quantity of original 24 volt bulbs, all of which are silvered on the inside but some are blacked on the outer surface while others are silvered. Both specifications are shown in our image. The bayonet fitting is stamped Crompton, a broad arrow property mark, 'GUNSIGHT'and stores reference 5L/2041. The bulbs show some storage wear and we can't guarantee they are still working but they are complete and undamaged. Each gunsight used a single bulb and spares were then stored in a small rack in the cockpit of fighter aircraft although trying to change the bulb in flight at close to 400 MPH must have proved interesting! The price quoted is for a single bulb and lease specify with your order if you require the silvered or black painted option. Bulb measures 2.25" (5.5 cm)
