notes: label: Description
content: This full-keyboard printing adding machine is manually operated. It has a metal case painted black with glass sides and green felt covering the keyboard. There are nine columns of black and white color-coded plastic keys. At the top of each column of keys is a red button for clearing the column. To the right of the number keys are repeat and error keys. To the left are non-add, subtotal, and total keys. The crank for operating the machine is on the right side and has a metal handle. At the front of the machine are nine number wheels that show the accumulated total. The wide carriage and printing mechanism are at the back of the machine, with printing invisible to the operator. The carriage can be set at several different positions. Either a roll of paper tape or single sheets of paper may be used. Changing the ribbon requires that the operator remove the case. Extensions on the right side of the case can hold a stand, but there is no stand.
