    A quote from the Plath company history tends to support Peter's view
    although it is somewhat ambiguous:
    "At the beginning of 1953 Johannes Boysen, together with the well known
    American navigator, P V H Weems, founded in Washington the firm of Weems &
    Plath, whose main purpose was to step up the sale of C Plath sextants in the
    The history points out that this association only lasted 11 years when C
    Plath pulled out, however it did not insist on a name change.
    The history continued, " As the US navy instited that the instruments used
    by it should be manufactured in the USA, C Plath granted the firm of Lowe
    Inc in New York a manufacturing licence for the C Plath sextants. Up to this
    day all Mark 111 sextants for the US Navy have been manufactured by this and
    a successor firm under this licence."
    These words were written in 1987 so according to the company's offical
    history Mark 111 sextants were indeed Plath's made under licence in the USA.
    Possibly David White was the successor firm to Lowe Inc that is referred to
    in the history. What date did your company pitch for the business?

    I don't know where you got your information, but my company, Nautech
    Maritime Corp of Chicago, Il,  bid on the Navy contract for the MK III, and
    it went to David White of Milwaukee. They also had a subsidiary, survivor or
    successor company called something like Scientific Instruments, Milwaukee,
    WI which made the Mod 2.
    You can read about this experience at:
    I was away from sextants from 1978 until just recently, but I was of the
    opinion that the W&H sextant was made by Cassens & Plath. I will not bet the
    farm on that one, but I will on who made the USN MK III Mod 0 unless what
    you say occurred while we were out of the country, 1978 - 1984, and during
    the following years when I was not involved with sextants in any manner.
