Nestler 0130 Multimath 0129 Polymath-Duplex pocket slide rules manual 1970 Germany

Interesting combination of 2 of the last and most elaborate pocket slide rule by Nestler is close to unused condition. Both come with their original leather sleeve, one has the additional formula sheet as well and there is a combination manual in German that covers both models. Everything is signed with the Nestler name and is made in Germany, Both slide rules have scales on both sides and are from the 1970’s. They are made of plastic with plastic reinforcements on the ends, one of the cursors has metal ends. Curser, slide rule and sleeve are complete and in very good condition with only small signs of normal use (minimal partial crack around a small screw of the cursor only). They measures ca. 18 cm or 7 inches. Check the attached video on how to work your vintage man tool : slide rule operation instructions!
