This is a rare find: an unopened, sealed K&E Log/Log Slide Rule in perfect condition. Specifically, this is a Keuffel and Esser Log Log Duplex Vector Slide Rule, #68-1439 (Old #4083-3), sealed in the original plastic.Complete with box, manuals (Log Log Duplex Decitrig #68-2047 and Supplementary Manual Log Log Duplex Vector #68-2051), Care Instructions and a Pocket Slide Rule catalog. The cursor and the slide move freely. I cannot stress the condition, everything is as it would have been in the campus bookstore in 1965.
The only thing I can find that is not perfect is the curled set of the manuals and some light foxing on the cover of the supplementary manual please see pics. For goodness sake, there isn't even a name written inside the tongue on the case...
The case is flawless - I haven't seen one so pretty in more years than I will say. The item "K&E 68-1439 Log/Log Duplex Vector Slide Rule New in Box Sealed Perfect Cond" is in sale since Sunday, November 19, 2017.
