Dancing Leg Calipers

Description
Calipers are used to measure round objects, both around the outside (machine parts, rifle shot) and from the inside (a rifle barrel). They were often included in cases of drawing instruments in the 18th and 19th centuries and shaped like the human body, mainly for the enjoyment of the machinist or draftsman. This pair is missing its set screw and has been welded into a fixed position. It has no identifying marks.
