Feliks (Felix) is a pinwheel, handcrank-operated mechanical calculator, built between 1946–1949 by the Moscow Plant of Calculating and Writing Machines (MZSPM) in Moscow, USSR. The design of the Feliks calculator based directly on the famous Odhner calculator, invented by Swedish engineer and entrepreneur, Willgodt Theophil Odhner, in 1890, working in St. Petersburg, Russia. Feliks calculators were manufactured essentially unchangeably from 1928 to 1978 (slight modification was made on the exterior shape in the 1970s, hence named to Feliks M). Registers: 9 x 8 x 13 Dimensions: - machine 275 x 140 x 126 (K) mm; - case 305 x 175 x 146 mm. Weight: 4,5 kg (6 kg with case). | ||||
