Not a Toy!... |
|
|
|
What's small, made of plastic, has less than
ten moving parts, is fun to play with... would you immediately cry
"a calculating device"? And yet - a calculating device it is, the Kes-Add Pocket Adder, manufactured by the Kesling Pocket Adder Company of St. Louis, Missouri. "An Adding Machine", says the box to prevent any confusion, "Not a Toy!" This device is simple and lightweight; and the ivory-colored plastic is surprisingly elegant, avoiding the "cheap" look typical of many old plastics. |

The Kes-Add has no Reset option; to zero it
before a calculation you must turn each wheel to the zero position,
by placing the stylus in the hole next to the "X" and rotating until
the X is hidden. Now you can add and subtract numbers by turning the
wheels with the stylus, Clockwise for addition, Counterclockwise for
subtraction, one digit at a time.
