    Douglas-Appleyard Arcless Sextant
    From: John D. Howard
    Date: 2019 Mar 29, 09:09 -0700

    Hello all,

    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?

    Thanks,

    John H.  41N 100W
