A compact square pinwheel calculating machine in dark grey enamel, the setting drum recessed into the body with a fan of short levers across its face, a row of numeral windows along the carriage, each window showing the single digit 0, carriage shift keys at the front edge, a plain shield-shaped badge on the front of the body, a crank with a black grip on the right, every other surface plain dark grey enamel, standing on a dark baize-covered table before a deep neutral background, a single raking light from the left raking across the recessed drum.
