Antique Thales CER Mechanical Calculator with Windlass System. Germany, 1930's

This lovely mechanical calculator is a Thales model CER in really good condition. The machine boasts a magnificent finish; the fine black-enameled finish that covers the metal case is restored. The white numbers that mark the digits of the mechanism also look clear and vivid, and the silvery-metal component parts only show a subtle antique patina created by the trace of time and the use. The calculator works fine and can perform the four basic arithmetic operations with fully reliable results. The Thales logo, located at the right of the machine, has been covered by the black enamel that protects the metal. Nevertheless, the embossed letters can still be perceived under the lacquer. Thales was a calculator manufacturing company that emerged in 1911, when Emil Schubert, a former Triumphator worker, founded his own factory in Rastatt, Germany. He associated with L. Haberer and Max Muller, a pushing entrepreneur with many contacts that made the business succeed. After many vicissitudes, in 1946 Mueller came back to lead the Thales-Werke again; Thales calculators kept on being produced until the late 1960s. The machine that we can see in these photographs works with a pinwheel system, a mechanism developed by W.T. Odhner in the late 19th century. This is a reliable and handy system; in fact, this calculator boasts an excellent working order in spite of being so ancient. The piece stands on its original solid oak wooden base and is attached to it by two solid screws. The base is supported by four circular legs that guarantee its stability. As ancient as reliable, this striking Thales CER calculator must still perform many arithmetic operations while displaying a great aesthetic potential.
