Reflector Sight Mk IIIN

Description

The MK III (actual name the Barr & Stroud model GJ3) was a British gunsight used in virtually all of their WW2 bomber turrets. The less common Mk.III N variant was made for night operations and had the glass protecting hood removed. These could be used in daylight operations too. There have been no attempts to check functionality. The glass looks good. This uses a 5L/2295, Type E, Double filament light bulb. This came from a museum collection.
