Faber Castell 2/82N Duplex with case aged 1970 Germany

The large slide rule was made in Germany by A.W. Faber & Castell and is called the Duplex 2/82N. This one comes only with the original box (no extra’s) and has clear signs of use and age. It is priced accodingly. The slide rule and cursor are both complete and in good condition, The box is almost complete but has a 2 pieces missing so it does not close to well. It measures ca. 38 cm or 15 inches long. This great rule is reinforced with metal pieces which are screwed in. The signs of use and age are mostly the yellowing between the scale lines.
