1914 Brunsviga MA Midget German Pin-Wheel Calculating Machine [link]Paper  abstract   bibtex   
Willgodt Theophil Odhner [Вильгодт Теофил Однер, 1845-1905] in 1875 invented his "Arithmometer", a versatile calculating machine. Driven by its technical director Franz Trinks, the German, Swiss and Belgian licenses were bought (for 10'000 Deutsche Mark) by Grimme, Natalis & Co., in Braunschweig, Germany in 1892, who presented the machines at the 1892 World's Fair (400th anniversary of Christopher Columbus) in Chicago. Advertized as a "Gehirn von Stahl" (brains of steel) the machine was said to familiarize with its new owner within 10 minutes. Grimme, Natalis & Co., was renamed "Brunsviga Maschinenwerke AG" in 1927. The Trinks-Brunsviga 1910 model MA pinwheel calculator is highly collectible and quite valuable, since it is a miniature "Midget" version of model A , also called the "Brunsvigula" and has 18 result digits, instead of model B's 13 digits. There were only 3342 machines built, my machine with serial number 26'912 is from early in 1914. The price was 600 DM in 1910, that was about a 10 month's income of a skilled worker. There are numerous operation guides, owners manuals etc. on the internet (free), most of them in German. It is recommended to study these manuals, since they contain tips and tricks, how to accelerate your calculations, that have been developed over a long time by the zillions of users. The machine is for sale at radio-antiks.com.
