Brass cylindrical case is mounted on a wooden base and capped by a brown insulator and brass disc. The base also has 4 brass plates on it, 2 at each front corner set perpendicular to each other with two brass pegs with insulator heads inserted into plates, one at each corner. The disc is divided by units of 10 (“0” through “90”, though “0” is repeated twice), and units of 200 (“0” through “1000”). Two brass arms swing around the top of the cylinder, touching a contact point at each of the divisions. There are two brass pegs with insulator tops. Inscribed on top “J. Carpentier/Ingr. Constr./Paris”. “109” is stamped on the wooden base.
