Further comments This is one of the inexpensive school slide rules that Faber-Castell made in years before WWII. It is one of the more complex ones.

Interesting to see that the reverse C/D scale is named "K" instead of teh usual "CI".

On the back of the box is a label of the shop that sold the slide rule: L. Morsbach Bürobedarf-Geschenkartikel, Linkgasse 5, Solingen. The price was then 10.75 Deutschmark.
