This is an early example of the Produx mechanical pocket calculator which was manufactured in Germany in the 1930s. It was designed by Otto Meuter (1892-1970) who was originally a designer in the Addiator factory but left to start his own businesses. In 1928 he founded Werkstatt Otto Meuter in Berlin and produced the first Produx machines. It is operated with a tiny stylus with a hook on the end, which is inserted in the holes by the numbers to move them up and down. This calculator probably dates from circa 1930.
