Aristo 867U pocket slide rule MIB 1970 Germany

This pocket variant of the 967U is made by Aristo from Germany. This full set contains the slide rule, the original leather sleeve, manual and the outer box. This model is 867u Darmstadt. The case and slide rule are complete and in great condition with only minimal signs of use and age. The price is for 1, but I have several, see picture with all 5, so slight variation from pictures are possible, contact me if you need to see the exact item. The case measures ca. 17,5 cm or 7 inches. Check the attached video on how to work your vintage man tool : slide rule operation instructions! There is also a long version, the 1067U.
