For this one we have a patent with good pictures in our list archive: http://fer3.com/arc/img/106506.fix_finder.pdf Unlike the bubble octant, these things are very rare on e-bay, from which I conclude that not so many were produced. Alex. P.S. My son who had a pilot training in 1994, and who works in the airspace industry says that he has never seen a sextant (and it was never mentioned during his training) until I showed him one.
