Scales: Wine and Ale Gallon Marks. Lots of very interesting additional Scales and Tables on the back of each slide. Dimensions = 12 long x 13/16 x 1.
Construction: Boxwood with Brass end tips. Brass end tips are in excellent condition (note, as the rule was made, there is one brass tip on each slide). Slides function properly (one slide is a bit tight). A couple of very minor nicks.
Some areas of light staining. Overall an absolutely beautiful rule. The item "Edward Roberts, UK. 12 (4-side, 4-Slide) Gauger's Slide Rule, 18thC.
