The 'Consul' Calculator

The numbers required are pointed at by arrows attached to the feet of the unfortunate primate (who has moveable shoulders and elbows), and the multiplication product can then be read at the bottom of the board that he holds between his hands. For division, the board is put on the number to be divided, while the animal’s left foot goes on to the divisor, and his right foot then points at the answer. We offer a reproduction of the 1916 “Consul”, of sheet steel with printed detail and prop-up sidepiece. 16.5 x 15 x 1.7 cm. Weight 190 g.
