So, as Frank has noted, this particular slide rule doesn't really do a whole lot, but... still... it is so fun! Honestly, I sooo wish I had one for my slide rule collection as it would go great with my Pan Am time zone calculators! See pics below - so easy to imagine 1960's business globetrotters carrying one of these in their aluminum Halliburton Zero attache cases! And then on the weekend, they sat on their sailboat and fiddled with one of the "Celestial Slide Rules" during cocktail hour!
