I don’t need this one. I’ve got my own in my office drawer.

In HS, everyone had to get a slide rule..of course, this was in 1961. I had a K&E log-log-decitrig..got pretty good at using it, too..

And somewhere in the basement, I think I still have a Frieden. Wonder if it's worth anything..or worth enough to did around for.
