About Keuffel & Esser rules
Keuffel & Esser was an American maker of drafting, surveying, and engineering instruments, based in New York and active from the 19th century well into the 20th. Its name is tied to slide rules, sighting levels, dividers, and drafting rules rather than bench woodworking tools, and the sample reflects that mix. Condition and completeness drive value: boxwood and steel parallel rules with crisp, unstained scales, dividers with tight joints and unbent points, and instruments still in their original cases or boxes with legible model numbers such as the N1783 stand above worn or mismatched examples.
The 3 sales behind these figures come from Ted Dawson Antique Tools (2) and Jim Bode Value Guide (1), and run from 2022 to 2026; 1 closed in the last twelve months. 1 listing for sets, pairs or lots of Keuffel & Esser rules was left out, because a set's price is not one tool's price.
