Measure Miles On A Map, Different Calibrations On Each Side.

Measure Miles On A Map, Different Calibrations On Each Side. German Made. Condition is "Used". This is a bit of old fashion technology. You run the small wheel in the base over a map and it calculates the miles. It must be geared in some attractive manner. The faces on each side give different measures. Of course, it is a piece of travel history never to be seen again since when was the last time you used an old fashion map! Comes in a nice leather pouch.
