    Byrd Sextant (or should it be "de Florez Sextant"
    From: Bill Morris
    Date: 2009 Aug 10, 22:41 -0700

    As glapook has perhaps revived some interest in aircraft sextants by kindly 
    posting attachments of several manuals, I have updated my blog on one of the 
    earliest American bubble sextant types, that patented by Luis de Florez in 
    1925, though it acquired Commander Byrd's name. The new post, at 
    www.sextantbook.com , includes some more detailed photographs of one of the 
    sextants, which is now fully restored. Look under "Aircraft sextants".
    If there is interest out there, I will be happy also to expand my blog post on 
    the Bureau of Aeronautics Aeronautical octant Mark I Mod 4.
