    Re: Sextant stands; was Lunar Distances: Graphic Methods

    The same thought struck me today -- I ran across mention of those devices
    for the first time while doing some google research on sextant mirror
    construction.  I had never known about them before.  I then researched
    sextant stands, but found only historical references, so it appears that
    perhaps nobody is marketing them any longer:
