6.10 K&E Rules by Model
The slide rules manufactured by Keuffel and Esser have been listed in other areas of the web site. However, these have been shown in chronological order. Since the Collection contains a relatively large number of K+E slide rules, the table below was created using the same rules as in Keuffel and Esser, USA but here listed in order of Model number, with sub-ordering according to Year.
