"I pre-marked my slide rule..."

Wow! Seems like it's still in use.

BTW, I bought one by Faber-Castell a while ago - with it's original packaging and manual. And i inherited another from my father with a teakwood core (!) for mercantile application ditto from Faber.

Please see also this as well as Albert Nestler and Don't know what a slide rule is for ;-)

Best regards, Karl
