    Vernier sextant
    From: Alexandre Eremenko

    After almost a year of intensive e-bay trading,
    I finally bought a vernier sextant:-)
    Since we were trading for the same sextant with George
    (and George won it) there were only three sextants on e-bay
    which I regrett that I did not win:-)
    Anyway, my new sextant is a C. Plath  with a vernier.
    So it is definitely made before mid 30-s, the seller says probably in
    It has 3 scopes, a zero-tube and an eyepiece filter.
    When it arrived, the scale was hardly
    readable. But after some cleaning (with oil)  it is OK now.
    I had to disassemble most of it to clean and oil, and today I finally
    made the first rough adjustment of the index and side errors.
    (Index error was 10' when it arrived).
    Now I am trying to fix the box (which arrived essentially in pieces:-(
    As soon as the weather permits I will report on the sights with this
    sextant. (I always wanted to compare the advantages and disadvantages
    of a good vernier sextant vs a modern one. So now I finnaly have
    this opportunity.
