Calculator Thales Patent Model CER, 1938.

Calculator Brand Thales Patent Model CER, 1938. Fantastic machine with original gray lacquered case endowed with different numbering registers in yellow and cream color, which make it very beautiful aesthetically. Technically it works perfectly with a smooth and correct movement. Crank or windlass mechanism with lever in cream color in clear contrast with the case. It has slight marks of use in the turning area of the crank that attest to its use, but do not detract from its value. The white and yellow enamel numerals are perfectly visible as they are pristine. On the upper front it has the logo with the name of the brand: Thales Patent, with a very decorative white lettering. On the back it has a golden sticker with the location of the brand and the serial number engraved: 124954. This type of machines are objects for science lovers. They have their origin in the XVII century, when the first adding machines were built, characterized by using a gear-based operation, which arise to alleviate the work activity of those people dedicated to accounting work. This type of machines were already much admired at the time, based on a system devised by Willigodt Odhner, the variant of the one developed by Leibniz in the 18th century. Emil Schubert started working for Triumphator in Leipzig before establishing his own company in Rastatt (Germany). He built the Thales pinwheel calculator in several versions since 1911. It is a basic machine, one of the pioneer windlass machines to use a spring-loaded car, which automatically makes steps to the left when the token at the front is pressed. Nostalgic piece that will delight a very special collector...
