    Sextant maker's mark
    From: Bill Morris
    Date: 2008 Jan 8, 23:00 -0800

    I am resurrecting an old micrometer sextant, ostensibly of Japanese
    manufacture. In the silver insert of the limb, at the right hand end
    is the kanji character for "tama"(precious stone or gem)in a 3 mm
    diameter circle. Below that in sans serif numerals is "No 606".
    However, on cleaning the bronze frame for repainting I found a 3mm
    high stamped mark next to where the horizon mirror is mounted. It is
    in the form of an anchor with two stocks, one of which is concave
    downwards. It was invisible beneath the paint.
    I have a vague memory that this is the mark of a German maker, in
    which case this is an example of badge engineering. Can anyone
    identify the true maker of this instrument, please?
