Wonderful Brunsviga 13ZK calculator made in 1930. This machine was manufactured in Germany by Grimme, Natalis and Co. from Braunschweig. The piece is in excellent condition, as attractive as the first day of use and in perfect working order. This model was made in 1930, but the company Grimme, Natalis and Co. obtained the German patent rights to the Odhner calculator (with pinwheel system) in 1892 and started produced this kind of machines under the Brunsviga name. The firm designed and commercialized many models until the early 1970s, when finally ended the production. Brunsviga 13 calculator was launched in 1926 improving the Brunsviga Nova design. From then on several models further types in the series appeared such as the 13Z, the 13ZK, the 13P and the 13M, known as a war-machine probably because of a commercial battle and also the war that was to come. The model that we can see in the photographs is very interesting for many reasons: it comes with an instruction leaflet, written in German and illustrated with beautiful etchings which depict two models of the series.
