I did the calculations in Excel and had them checked by expert dialler Tony Moss. I used Illustrator for the 'delineation'. The style of Lord Armstrong's capital A, and the little flower motif attached to each half-hour line, were taken from engraved cutlery preserved at Cragside.
The Latin means 'Strength in Arms, Strength in Horticulture'
