    I wish the hell I could remember where or when I heard this and who told me,
    but some  years ago when I was in the US a former naval officer told me the
    same story: the C.Plath had actually manufactured the Navy Mk III and that
    it was in effect a "shell game". This is not to suggest any illegalities;
    only that the Navy wanted a certain type of sextant and Plath was the
    Perhaps there is a current or retired US Navy man out there that can
    enlighten us.
    As for the idea that Cassens and Plath may have manufactured the Weems and
    Plath models, this likely stems from the fact that the Weems and Plath
    frame, with its circular centre, was identical to the Cassens and Plath
    frame. It should be noted however, that C.Plath made a slightly cheaper
    version of their Rolls Royce model; the frame of which had the circular
    centre. As far as I know, Weems and Plath marketed C.Plath products.
    It all seems very incestuous doesn't it?
