    Old Sextant on German money
    From: Alexandre Eremenko

    Dear list members,
    Many of you probably know that there is a picture of a sextant
    on the famous German 10 DM bill dedicated to Gauss.
    (Unfortunately, this money bill was removed from circulation with
    the introduction of Euro. I saved a few of them, unfortunaly very

    But the most curious feature of this sextant is the Index glass.
    It looks like consisting of two pieces, the kind of an index glass
    I've never seen before.
    Can anyone answer what is this?
