Graphoplex 697 electric slide rule container 1960 France

This slide rule comes in the original  container and was made by Graphoplex from France. It is the shortly produced duplex model. It seems there was no specific instruction for this model because it came with a model 1600 / 1614 instruction in Dutch. The one I sold 2 years ago came with a Neperlog 690a instruction in German. The rule itself is made of plastic, as well as the cursor. Curser and slide rule are complete and everything is in great condition with hardly signs of no fading or discoloration and perfect rubber feet. It measures 33 cm or 13 1/4 inches long.
