Keuffel & Esser...

I have a K&E slide rule, manufactured sometime before the 1960s as best I can tell (patent date 1919, very battered but robust leather case). I like to think it may have been used by an engineer working on the Apollo Project. Had a nice circular slide rule also made in the 1960s (purchased new), but it was lost to multiple moves.
