Summary
Outside Calipers - Made up of two semi-circular symmetrical sections, joined with one rivet. The mid section of the calipers feature measurement scale. A grub screw would have been in place to maintain the measurement made, now missing. The tool is used for measuring the 'outside' diameters of wood or metal, eg. for axles, hubs.
