This full-keyboard, printing adding machine has a steel frame painted black and green There are eight columns of color-coded black and white metal keys with digits written on paper and covered with clear plastic (the keys resemble those on early typewriters). Complementary digits are indicated on the keys. The total appears in eight glass-covered metal windows over number dials at the front of the machine. There are total and non-add keys left of the number keys and a repeat key on the right. The total key also clears the machine. A metal crank with a wooden handle on the right of the machine operates it. Behind the keyboard is a two-colored ribbon, printing mechanism, and fixed narrow carriage. There are nine type bars, eight for digits and one for special characters. There is a serrated edge for tearing off the paper tape.
