Sextant Kit, Aircraft, Type A-10A, Fairchild Camera

A very nice, working, WW2 vintage aircraft A-10A bubble sextant in its original wooden case with mounting hook and battery-power accessory for nighttime illumination used for celestial navigation.  Used across many versions of US Army Air Force aircraft with navigator crew during the era, such as bombers B-17 Flying Fortress, B-24 Liberator, and B-29 Superfortress, and transports C-46 Commando, C-47 Dakota, and C-54 Skymaster. The sextant would be suspended from the plexiglass astrodome in the ceiling of the aircraft while the navigator sighted a select stars, plotting its change in location with the timed plotting mechanism to determine aircraft course. Photocopy of handbook/parts catalog included.  Here is a pdf copy of the handbook to download at no charge.
