Keuffel Esser 68 1130 Deci-Lon 5 pocket slide rule full set 1960 USA

This is a high quality build pocket slide rule with elaborate calculation options through 26 different scales. This great rule also come in the original box with the original leather case as well as additional paperwork (this was sold without a manual). The Deci-Lon model is the best slide rule made by Keuffel + Esser Company from the USA before the went out of business. It is rarely seen in Europe since it had to compete with the Faber Castell 2/82N and 2/83N slide rules. This K+E rule is in great condition, hardly used , if any and the extra items in the box are kept very well and look close to new. The card board box did it’s job well in protecting everything inside and only sufferd a bit from storage. The box is complete as is the plastic inside, with only a few scuffs on the corners. This model Deci-Lon 5 measures 18,5 cm or 7 1/4 inches wide. Check the attached video on how to work your vintage man tool : slide rule operation instructions!
