    Re: Navigation School Workbook 1886

    Thanks Frank.
    As long as we are posting e-bay listings of interest, the list might want to
    check this C.Plath out. A very good deal and a rare item comes with it: a
    Plath Bubble attachment.  The attachment alone is worth the $800 for the
    opening bid.
    But hurry: the bid ends in one hour.
    Now check this item out:
    This is for a C.Plath yachtsman. I have never seen the like of this before
    and I have two books on C.Plath sextants. Would appreciate it if anyone
    could fill me in on the details of this little gem.  It looks like a
    lifeboat sextant.
