Slide Rules and Slipsticks - in the 1960's B.C. - i.e. (Before Computers)
Love it – dem’ was the days of real computing, unlimited memory, and engineering hard drive.
Yours looks like the famous, highly desired ... K & E Log-Log-DeciTrig-Duplex “slip-stick”. Engineers weren’t really entitled to own one of those, unless they could say that quickly, with a drink in their hand.
Way cool Pickett man myself – its case, almost like having it slip into “Corinthian leather”, but probably just cowhide :-)
K&E rare Bamboo style was fine ... but Pickett’s unique engineering design with its specially chosen Green spectral colour, for easy visibility with bleary eyes when cramming in the middle of the night, Magnesium alloy with tiny ball bearings at the slide’s ends for high speed computing – engineering heaven. Works on both east and west side of its cursor, easily finds home position on reboot, even works inverted for the log-log and exponential functions ... and BEST of all ... never needs AeroShell-33 relubrication :-)
However, my Radio Astronomy engineering prof, used his Abacus, to prove I didn’t need to always run his 3C-273 strip chart data through the PDP-11. I think his was an 8-Bead, (later called a Byte), “flip-stick” calculator.

They were only cool if they were full. <G> …but real cool was the slide rule slung from your belt in its case! Talk about a chick magnet…ah, the old days!
