    In retrospective I realised that my question was not completely clear, 
    but above answer still does not answer my question: what I would like to 
    know is if it was explicitly written down that those 7 observations were 
    done using back-staffs.
    If so then I would like to know were (original logbooks or 
    articles/books that used those logbooks as primary sources), so I can 
    refer to it in an article I am currently writing.
