It is cleared by pulling a small bar on the top and the change from adding to subtracting is made by raising a small flap on the face of the Correntator. This Correntator was made for the British Market in the 1920’s probably in France it is marked Foreign in the lower right corner. The correntator comes in its original black leather, notebook like, case. One page of the original instructions is retained on the inside of the case.
