Gunner's caliper housed in a leather case in the shape of a small sword sheath with gilt brass trimmings. The case is divided into four compartments, one of which is occupied by the square-shaped instrument. The caliber's four sides each carry a division into 24 equal parts, and decreasing divisions into 400, 1,300, and 2,100 parts. The "Munchen" inscription on one of the sides of the rule suggests a German origin. Provenance: Medici collections.
