- Description
- This full-keyboard non-printing adding machine has a steel case painted tan. The eight columns of key stems have nine key stems in each column. The green and white color-coded plastic keys deteriorated badly and have been removed. A row of nine numeral wheels is in front of the keys, and a second row of nine wheels in front of the first. A metal handle with plastic knob is on the right side of the machine and an all-metal handle is on the left side. Behind each result window is a rotating decimal marker; behind each marker for the numeral wheels in the front row is a button that can be depressed to move a cover over the result wheel. An opaque white plastic cover came with the machine although it does not fit it.
