label: Description
content: This adder was among those invented by Otto Meuter, a German. Meuter was first associated with various versions of the Addiator and then, in the early 1920s, formed a company with J. Bergmann to produce the ProCalculo! and the Correntator. In 1928, he began to sell the Produx. After World War II, the Produx was still manufactured in West Germany, while the East Germans sold a similar machine called the Record.This machine dates from after World War II.
