Nestler traffic slide rule container manual 1976 Germany France Holland

This slide rule is comes with the original signed container, both made in Germany by Nestler. This model is a very interesting Traffic model. It has text in French and Dutch on the rule for measuring convoy distance and number of vehicles. It comes with a 2 sided instruction sheet in Dutch. I am assuming this rule was for use with large (international) organisaties like the Red Cross and army. The Nestler name and model is on the rule, the Nestler name is also on the container. It is also signed with the German company that distributed this rule as well as the usage of the rule in French. It is made of plastic and has a simple cursor Curser, slide rule and container are in good condition with small signs of use and age. On the back the number 1976 is impressed. It measures ca. 28,5 cm or 11,5 inches. Check the attached video on how to work your vintage man tool : slide rule operation instructions!
