Made in Soviet Union, Russia, Kursk, factory "Schetmash"
In 1924, Felix Dzerzinsky, founder of the Checka, started the manufacture of these pin-wheel machines as a mean to provide a source of labor for young people in Russia. Initially, Felix calculators were produced in Moscow in a factory which later became the headquarters of the KGB (Felix Dzerzinsky was also chief of the KGB). They were manufactured until the beginning of the 80's. As is was typical in Russia, the calculators were manufactured in many factories, most of them came from a factory located in Kursk. The gears of Felix calculators were made of a low resistance Zinc alloy instead of the steel and brass used in Odhner calculators.
