    David,

              I take it that the "2014 document you posted on using PostScript" you are referring to is the code for Bygrave/MHR1 scales. The was a slightly later update to that and the most recent files available and other related materials are summarized here http://fer3.com/arc/m2.aspx/Buy-build-modern-Bygrave-slide-rule-Stuart-oct-2019-g46008
