      I will post a detailed reply tomorrow, but I have one question for you to
    ponder. You mention that the phrase "pillar sextant" sometimes referred to a
    sextant mounted on a stand. And I don't think that's true in the first
    place. I haven't found a single case of this usage in the lit. Do you know
    of one? As a corollary, is it possible that it's only you (and maybe a local
    museum in Oxford which you mentioned once before) that refer to a sextant on
    a stand as a "pillar sextant"? In the period, the term was used for the
    well-known double-frame design, originally patented by Troughton. For
    example, in Lecky's sextant buying suggestions, he writes, "Give the
    preference to a "pillar" sextant over one whose framework is cast all in one
    piece" (Lecky's Wrinkles in Practical Navigation, 1884, via Google Books).
