Faber Castell Novo Duplex 2/83N case aged 1970 Germany

The well known slide rule that was made in Germany by A.W. Faber & Castell and is called the Novo Duplex 2/83N. This one comes only with the original box and inlay 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 complete but the case lid has turned yellow. It measures ca. 38 cm or 15 inches long. This great rule is reinforced with metal pieces, the screws have darkened a little due to age. There signs of use and age are mostly the yellowing between the scale lines (if you want it to be near mint, check out this one).
