about the A-10 A Bubble Sextant:

Thomas L. (Tommy) Thurlow worked with the Fairchild Aviation Corporation to develop a small and rugged aircraft sextant suitable for military use. The basic form received Army designation as the A-10 in 1941. It has a plunger that the navigator could push when making a shot, that would make a mark on a white plastic disc. After taking several shots in quick succession, the navigator would remove the disc and determine their median value.

This example (an A-10-A) was made in 1944 Since more air sextants were needed, the Army signed asimilar contract with the Agfa-Ansco Division of General Aniline & FilmCorp. in Binghamton, New York; this contract was worth $2,259,625 and includeda $7500 payment to Fairchild for \'flow charts, material, specifications, billsof material, engineering Etc.
