Antique Thales C1 Windlass Calculator in good working order. Germany, Circa 1919

Elegant antique mechanical calculator with pinwheel system, in good condition and perfect working order. It is a Thales C1 model made in Germany circa 1919. The calculator is in really good condition and works fine. Its component parts and pieces move softly and fluidly so it is a real pleasure to perform arithmetic operations with it, always with exact results. The machine preserves its original solid wooden base and is great-looking, with no visible traces or rust or wear. At the front of the calculator, on the black-lacquered surface the Thales decal stands out. It is engraved in the metal and painted white. Thales was founded in 1911 by Emil Schubert who had been a foreman for the calculator factory Triumphator-Werke. Schubert decided to start his own calculator business together with L. Haberer and Max Mueller. In just a few years the company became quite successful. After many vicissitudes, the National Socialists made Schubert leave his company without taking the patents; the entrepreneur, then, decided to start another business to make calculators under his own name. After World War II, Max Mueller took over the company again, now located in Rastatt. The firm kept on active until the late 1960s. This fine pinwheel machine is based in the aritmometer designed by W.T. Odhner in the late 1870s. It mounts chromed-metal mobile parts and black bakelite knobs. The numbers are engraved in the metal casing and are painted white; they remain clear and legible. One of the silvery metal parts bears the engraved serial number 7776. The wooden base is oak-veneered; it shows some signs of wear due to the trace of time that can be easily restored by a professional. This wonderful pinwheel calculator is waiting to stand out on the desk of a lover of turn-of-the-century machines.
