31cm/12 inch wrought iron wing dividers dating from the 18th century, most likely German. Two thumbscrews and a butterfly wing nut with hand-threaded screw allow for very fine adjustments of the legs. The dividers are beautifully decorated throughout with fine file worked details. In excellent condition and fully functional.
From the “Geometricum” collection by Markus Geissbuehler, Switzerland.
