    Re: Russian barograph
    From: Aubrey O?Callaghan

    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.

    Hi everybody,
    I've just received a Russian barograph that is going to increase my collection of nautical instruments.
    Does anybody have a manual for the use and maintenance of a similar barograph?
    Help would be greatly appreciated.
    Bests,
    Federico Rossi
