Graphoplex 6245 Electric 55cm 22″ slide rule box papers 1960 France

This double length slide rule comes in the cardboard box, with manual (wrong model) and card, all made by Graphoplex from France. This model is the 6245 double length Electric slide rule. It has scales on both sides of the inner slider. The number 6245 cannot be found on the slide rule so that is probably the mix up with the model (Rietz double length is model 6250). The rule itself is made of plastic, the cursor has metal edges and is specific to this slide rule. The cursor has 1 long and 2 short hairlines, window with hairline on the back as well. Curser and slide rule are complete and everything is in good condition. There are no structural problem but there are some deeper scratches on the back. It has a French instruction manual and formula card. The case is complete but has tape on the far edges. Case measures 58 cm or 23 inches.
