Description

1947 Keuffel & Esser K&E N4080-3 Log Log Duplex Trig Slide Rule w/ Leather Case
You get a nice 1947 K&E Slide Rule N4080-3.
It belonged to my father-in-law who used it at Johns Hopkins Applied Physics Lab in the 1950s - 1970s.
The slide rule has some writing etched into the aluminum end pieces as shown and some light yellowing from age. Slides pretty well.
Leather case is 13" long and is in excellent condition as well.
