Calculigraph slide rule and charts

Published
At a time when high-quality slide rules were very expensive there was also a market for very basic, low-cost slide rules, which may be typified by the Colyer-Noyes Calculigraph Model, made from two fabric boards with logarithmic scales. The functions are the basic ones of multiplication, division, proportion and square root.
