The machine combines the capabilities of a printing adding machine with the ability to print a few letters. It is a modification of the Allen Wales adding machine produced after the National Cash Register Company had acquired that company.
The device has a gray-brown metal case and nine columns of green and white color-coded plastic number keys. Odd-numbered keys are concave, even numbered keys, flat. Immediately to the right of these keys is a column of red keys marked with letters designating the significance of the number entered (e.g. one key reads “TX”, perhaps for designating taxes). To the right of the keyboard is a lever, and, to its right, a column of four function bars and keys. To the left of the keyboard are four other function keys. Above the keyboard is a row of nine openings under a glass cover.The openings show digits in the total. Behind this result window are two metal levers, one for tabs and the other for non-printing.
Behind the openings is the printing mechanism, with a red and black ribbon. The spools of the ribbon are under metal covers that are screwed in place. The mechanism includes a set of five wheels that can be set to a date. Behind these is a sheet of clear plastic, the carriage, and the narrow paper tape. The carriage is 39 cm. (15 1/4”) across, and divided into two parts. The narrow section on the left side takes a narrow paper tape, which is 6 cm. (2 1/2”) wide and is turned by a wheel on the left. The wider section on the right side takes pieces of paper and apparently was used to enter both figures and the date. The machine has a rubber cord and four rubber feet.
A tag on the front of the machine reads: 158 552366. A mark on the back of the machine reads: MANUFACTURED BY (/) THE NATIONAL CASH REGISTER COMPANY (/) OF DAYTON, OHIO, U.S.A.. AT ITS (/) MANUFACTURING DIVISION (/) AT ITHACA, N.Y., U.S.A.
