National Class 2000 Bookkeeping Machine

This is a relatively late example of an NCR Class 2000 accounting machine built for department store use. NCR had introduced the Class 2000 as a way to register several totals in 1921. From the mid-1950s, it was gradually be replaced by electronic accounting machines.
The machine has a ferrous metal case and metal mechanism. The printing mechanism is at the front left and has space to print two forms simultaneously. Paper is in one of these spaces. A set of three rows of numbered keys at the front left determines the line on which a number will print on a form. These keys are numbered from 1 to 21.
The back part of the case is rounded like a cash register. It has a set of six columns of plastic keys on the right, which are designed for entering identification numbers. The leftmost column is lettered from A to K (top to bottom). The five other columns have the digit keys from 0 to 9, going up. At the center left are six columns of keys for entering numbers, with nine keys in each column. Between these sets of keys are a motor bar, a lever that can be set according to the operation to be performed, and three partial columns of function keys. Left of the digit keys are two columns showing the results accumulated in several different registers. The machine has a keyhole with key.The electric cord is at the back.
A mark at the center front reads: National. A tag at the front left reads: 6101190 (/) A2146 (64UP). A mark on the center front at the base reads: The National Cash Register Co. (/) DAYTON, OHIO, U.S.A.
