Following a thread on the Douglas protractor I came upon a refrence to the Douglas-Appleyard Arcless Sextant. I have found a pix and a short discripsion of it but very little else. It is mentioned in a NACA report from 1922 but no pix.
The sextant seems to be used in aircraft and surveying. Does anyone know of or have any more info on this sextant?
