Enjoy and use this part of history as this slide rule was used to help design the largest plane in the world at its time in the 60's 70's! This was my fathers Slide Rule while he was an Aeronautical Engineer for Lockheed (now Lockheed Martin) out of Marietta, Georgia in the 60's, 70's. I hope this goes to a collector, or engineer or even better to an Aeronautical Engineer! As shown in the pictures, this slide rule comes with the original box as shown with some staining and aged wear as well. Please look at the pictures for condition.You can see there is some rust on the metal part of the belt loop and some light corrosion on the slide rule metal part, which has not hindered or affected functionality at all. There is also some light discoloration on the rule. I have described this as best I can. The item "Vintage Post Versalog Slide Rule 1460, 016632 Original Box" is in sale since Sunday, July 30, 2017.
