The Schetmash VK-1 is a 10-key handcrank-operated mechanical calculator. The mechanism is based on an inverted Odhner's pinwheel-type calculator - moving the setting register instead of the moving result/revolution carriage). The VK-1 is a clone of a Swedish Facit TK (1936-1954). The "Soviet Facit" was manufactured from 1951 to the late 1970s in Schetmash factory. During the Soviet era this machine was in use at the Tarvastu forestry district office of the Viljandi Forestry Management unit (Viljandi Metsamajandi Tarvastu metskonna kontor) in Southern Estonia. After the end of its service life, the machine was kept as a memorabilia by the former employee and found its way into my collection in 2026. Registers: 9 x 8 x 13 Weight: 6,4 kg. Dimensions: 18,5 x 30 x 14,5 cm. | ||||
