Re: Russian barograph

    Frederico,
    I purchased one in the Canaries about 7 years ago, same time as I bought my
    Cetus sextant. Mine has a white plastic case. It has only 5 bellows. (I
    believe 7 is normal today). I see one on ebay today:
    http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=361&item=2242006992&rd=1
    One things I noticed is that the metal is very "soft". The metal pins
    supporting the axles are of a different metal to the supports. I have had
    severe corrosion and have had to epoxy the pointed pins holding the
    spindles in place. My boat is in Caribbean in a dry warm environment. So in
    Northern climes this may be worse, You may not want to keep it aboard.

    I notice in the picture I have attached that the baragraph paper is too
    wide and has been folded over. I obtained the right size paper from Kelvin
    Hughes in UK.

    Aubrey.
