    Hi All
    I'm new to this group,so I thought that I would start with a bit on an
    My name's Max and I am a collector of memorabilia from the German
    Kriegsmarine of WW2.  My collection can be viewed here at my site:
    I have decided to join this group, as being a collector of Naval items
    I have a keen interest in Navigational Instruments.
    Whilst doing a Google search for some items that I have in my
    collection (and items that I am looking for), I came across an
    archived message regarding a couple of instruments that I have.
    The Instruments in question are the Dennert & Pape (gwr) HR-2 and
    MHR-1.  I have neen trying to gather information on these Navi
    Insruments to help understand them a little better.  I know of a few
    in Museums around the Globe and a couple in private collections.  I
    would like to share mine with members of this Group, as these are
    seldom seen anywhere.
    If you click on this link (or copy and paste), I have posted a few
    stills for all to see:
    You will also be able to see the rarely seen Bygrave AML Position Line
    Ruler, that the MHR-1 (and the HR-1 Luftwaffe equivalent) was based
    The only other Navigational Instrument that keeps eluding me is the
    Carl Zeiss Jena (blc) ARG-1 (Astronomisches Rechenger�t 1).  This was
    a Luftwaffe intrument, but the Kriegsmarine ordered a small number to
    carry out trials on U-boats.  These proved so successful, they were
    adopted by the U-boat Arm.  The only difference between the Luftwaffe
    and Kriegsmarine instrument, is the letter 'M' on the top of the
    casing.  Everything else (including the FL~~~~ Luftwaffe code)
    remained the same.
    If anyone knows of one.....
    All the very best and thank you for taking tme to read my post.
