Doesn't "Teledyne Post Versalog" have a nice, techy ring to it?
Certainly one of the most popular rules in the world, and not just because we see Cal Meacham using one in This Island Earth. An awfully pretty slide rule.
The picture sucks because this is the one instance of me being a typical collector dork: the rule's still vacuum-sealed in a plastic bag.
I still can't figure out how Teledyne went from owning Post to making Water Piks.
