STW-10 is an electromechanical calculator produced by the American company Friden in 1949. It’s a slightly modified version of the ST-10 calculator, which was marketed throughout World War II, and which saw the participation of Carl Friden, founder of the company called after his name, in its design planning. Thanks to its solidity, reliability and (for the time) convenience, STW-10 met with large success, especially with insurance companies, and its production went on until 1966.
