All About Slide Rules Book (PDF)

[rkf]

I'd like to thank Egan for the useful link to the PDF, and Mark for the hint regarding Faber-Castell online shop. Now I have not only one more slide rule in my collection (Castell-Duplex 62/82 N), but that one awakened the curiosity of a colleague, who afterwards asked me to explain the basics of slide rule calculations, and thereafter ordered at Faber-Castell for himself.
