All The Rules...
Thus begins a comprehensive picture list of all the slide rules in my collection. I have duplicates of many of the rules, but will only show one such sample if that happens, with the exception of the K&E rules. Each K&E sample will be listed, since their long history and continuity of a model line will show the evolution of the production of those rules.
Note: This page is under-construction and samples are slowly being added. Only a fraction of my rules yet appear here as of July 3, 2024.
