    Re: Traditional navigation by slide rule

    Regarding decimal vs. sexagesimal, the K&E 4080 family may be a good
    basis for comparison since it was made in both flavors. The exemplars
    below were manufactured after K&E totally changed their model number
    system. Nevertheless, they are siblings from the 4080 family and have
    the final scale arrangement. (K&E changed the scales several times over
    the years.)

    Maybe this page at the International Slide Rule Museum?

    Here's a Pickett N3 slide rule simulator. I think the N3 is the best of
    the big Pickett rules. I own an N4 and N803 but wish I had an N3!

    The simulator may be downloaded to your computer and run off-line. There
    are other slide rule choices available, but I think all are Pickett rules.
    
    I don't know how hard it is to do one of those simulators, but it may be
    a good way to prototype the navigation slide rule. Some things you don't
    notice until you use a rule.
