Gauger's scale

An English gauger’s scale, probably 18th century. The units measured on it are: Hogshead, kilderkin, barrel, etc. It may have been the possession of a tavern keeper employed to measure his wares. Gauging, or measuring the liquid volume in a cask or barrel was an important mathematical activity from the Middle Ages through the 19th century. Johannes Kepler devoted a book to the subject.
