"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 «The Crux of the Biscuit is the Apostrophe»
