    I didn't find any mention of it in my blue covered 1962 edition.

    Thank you, Gary.
    
    When I sold my house three years ago, I donated what I could of my nav
    library and (sigh) had to just pitch a lot of it - including my
    collection of every NA from 1965. I have in my mind that a picture of
    the device was in one of my Bowditch's - as I recall it was an edition
    with a dark blue cover, whereas I think the 1977 was medium  green?
    The description in the pages you sent sure fits, though.
    
    Thanks again,  Hewitt
