The Substitution Balance by W C Bochkoltz, ca. 1833

The Bochkoltz balance of the Physics Department of the University of Lyon, France. Most probably this balance was made by Delieul in Paris around 1833. It could be viewed as a forerunner of the modern single-pan substitution balance as introduced in the second half of the 20th century.
