    | At that same site there's a short bio on the inventor, Battenberg. He

    | distinguished career in the Royal Navy. That is, until the outbreak of
    | war in 1914. Later he took the surname Mountbatten.

    | Getting back to the device itself, I found that The National Maritime
    | Museum in London has one:

    | According to that page, list member Peter Ifland did a writeup on the
    | Course Indicator in Navigation News back in 2000.
    | Here's one for sale, price 475 Euros. Either this one is a different
    | variant, or there's a lot of stuff missing.

    I have a copy of the RIN's Navigation News for November/December 2000, on page 14 of which is an
    article by Gloria C Clifton and Peter Ifland entitled "A slice of history: The Battenberg course
    indicator". Gloria is curator of navigational instruments at Greenwich maritime museum, and now is
    the museum's director, I understand. Peter is an occasional Nav-L contributor, and author of "Taking
    the stars" (about sextants, etc) , and a co-author of "Line of position navigation", recently
    discussed here in relation to Sumner lines.
    The instrument is nicely explained, as you would expect from those authors, with a clear diagram. It
    occupies two A4 pages, which I am happy to scan if requested and send to individual email addresses.
    Just ask. Don't expect a response within10 days or so, however.
