In very good condition comes this pocket slide rule by Faber Castell, model 62/83N version. In the 1970’s these were amongst the best slide rules by Faber Castell. The slide rule comes in the original signed leather sleeve and with the manual in German. The rule, sleeve and manual are all in very good condition with small signs of use and age (minimal yellowing around the slider only). The sleeve measures ca.22 cm or 9 inches long.
