    German Sextants
    From: Nicol�s de Hilster

    Dear group,
    The former curator of the Netherlands Maritime Museum in Amsterdam 
    Willem M�rzer Bruyns (currently holding the National Maritime Museum's 
    2005-07 Sackler Research Fellowship in the History of Astronomy and 
    Navigational Sciences) posted the following question on the Rete group, 
    which he would like to have cross-posted here and on the Yahoo Sextants 
    group as well (the latter is already done). If anyone has an answer I 
    can pass it through to the Rete group.
    many thanks,
    Nicol�s de Hilster
