notes: label: Description
content: By 1894, when this device was made, the National Cash Register Company had developed an adding mechanism in which digits were indicated on the rim of rotating wheels. This is such a mechanism. The three wheels could rotate to show totals as high as $9.99. Four other wheels on the left side each have the digits from 0 to 9 around the edge. The mechanism is mounted on a white wooden display board.
label: Description
content: A mechanism of this type was used in the NCR Model 79 cash register (see object MA.316701). NCR went on to develop a more compact mechanism that could represent eight totals, rather than just one, on a single shaft. See object MA.316704.
