    Ah so. On mine, the graduation and the numbers are painted black. But
    then I think I payed 10 dollars more for it than you!

    No modern sextant that I have ever seen does not have a vernier on the
    drum. Check out the Astra, Freiberger or newer models from Plath.

    True, this can happen. There is supposed to be enough friction to hold
    the arm in place, but as Chuck Taylor pointed out, the manufacturing is
    so uneven that it is difficult to generalize what quirks a particular
    model of a Davis sextant might have.
