Walther Antique Mechanical Calculator. Germany, 1960's

Amazing Walther mechanical calculator made in Germany in the 1960s, in very good condition and working order. The striking machine includes a pinwheel system similar to those of the ancient arithmometers designed by the engineer W.T. Odhner, based on Leibnizs discoverings. The calculator is complete except for the plastic knob of the top left lever, currently missing. However, this detail does not interfere at all in the machines performance; it still makes it possible to carry out the four basic arithmetical operations with flawless outcomes. The metal casing bears an attractive beige enameled finish, really well preserved and with just some slight signs of wear. To the left we can see the embossed WALTHER decal in golden lettering on a black background. The white numerals remain bright and visible and the red and white plastic knobs make a fine combination with the rest of the calculators colors. At the back of the machine there is a metal plate with black background where we can read the manufacturing companys name, the calculator model (WSR 160) and the serial number 171171. Every lover of antique machines will appreciate the charisma and good working order of this wonderful Walther mechanical calculator.Walther calculators - History The brand Walther stars out in 1886, when Carl Walther founded a gun factory in Thuringia, Germany. In 1924 the company decides to broaden production and launches their first calculator, a pinwheel machine based on Odhners design. In 1929 they launch their first electric calculator; in those days, 2.000 employees worked for the company. During WWII their production is focused on military equipment; after the content, they lose the factory and Fritz Walther starts a new business with some of their engineers. In the 1960s the factory produces accounting machines, printing systems and data collection systems for computers. The calculator wars started by Japan in the early 70s was the beginning of the end of Walther Office Machines, which eventually closed its doors in 1974.
