Faber Castell 12/82 Precision slide rule container 1970 Germany

Interesting late slide rule by Faber Castell, model 12/82. It is a rarely seen version made at the end of the slide rule era and classified as a “Precision” model. The slide rules come in their original signed outer plastic container only (dented corners). The rule is in complete and in good condition with signs of use  and aging (yellowing). The box measures ca. 33,5 cm or 13 1/4 inches long. Check the attached video on how to work your vintage man tool: slide rule operation instructions!
