Ducat coin scale
Nuremberg Pic CS 8 Ducat scales by Friedrich Täuber, Nuremberg 1744 +. It is a fascinating combination of equal-arm two-pan balance and pendulum or inclination balance. the left pan is heavier than the right pan by an amount equal to the weight of a gold ducat, so NO weights are needed. If the coin is underweight, the beam comes to rest in a inclined position, and the amount underweight is indicated on the quadrant fixed between the pointer and the beam.
The paper label say: " Ein Wäglein ohne Gewicht einen Ducaten zu wiegen auf den Bogen für die Eße
