Description
The Mk III Aircraft Gunsight was adopted by the RAF as the standard turret and free gun sight for their aircraft. It consisted of a detachable lamp unit and an upright sight head. The lamp unit is removed by depressing a small button on the bottom of the housing, revealing the bulb and circuitry (this example is quite tight). The brightness of the bulb was adjusted by the gunner by rotating the rheostat knob. The bulb illuminated the reticle which was projected through the lens onto the glass reflector from below. The glass reflector is contained within the housing above the lens. The reflector housing has a flip-up sun screen, which is engaged by turning a small knob on the side.
Made of aluminum, steel, and glass, and dating around 1943, this is an EXCELLENT used example. There are some light scratches and wear from, however it retains 95% of its original finish! All the glass is original to this sight, and the data information is 100% intact, clearly indicating the model and type. The aiming circle/crosshair is also present! The original wiring is present, however the plug is missing (easy to replace). Would make a VERY NICE addition to any collection, display, or simply as a conversation piece!
