    Re: Ruminatons on Bygrave and Hohenrechenschieber scale markings

    Brad,

    Exhausting indeed! I had not anticipated that there would be this level of variation through the scales. It will make programming them in PostScript a bit more challenging. The MHR1 scales stand in contrast to the Bygrave markings for which a given subdivision (1d, 30', 10' etc.) seems to have the same length regardless of where it appears along the scale. Thanks for your efforts in completing the document. I think we now have a quite valuable record of the details of the device,

    Regards,
    Robin
