The Odhner Arithmometer was a successful mechanical calculator invented in Russia in 1873 by W. T. Odhner. Shut down by the Russian Revolution, the family returned to Sweden in 1917 and resumed manufacturing under the brand "Original-Odhner." The design was widely copied by other companies. This version has braille characters on the readout rather than the original print numerals.
