Info: A version of this slide rule is said to have gone to the moon with Buzz Aldrin on Apollo 11.  Because of this, it's known sometimes as the "Apollo Rule."   

This, of course, has made it very collectible, whereas it becomes hard to find a copy for less than $50...MUCH more if it comes with the original box, case, and documentation.
