Buroughs Series F Bookkeeping Machine

This full-keyboard, printing electric bookkeeping machine has a gray metal frame with streamlines and 11 columns of square plastic gray and white color-coded number keys. Left of these are three columns of keys used to denote the date and type of transaction. Possible years are 50 (1950), 51 (1951), and 52 (1952). Right of the number keys is an addition bar and three columns of function keys. The function keys may relate to operations carried out when the carriage is in three different positions. The printing mechanism and wide carriage are behind the keyboard. No stand and no exterior motor are present. A cord extends from the back of the machine.
A red paper tag attached to the object reads: PATENT DEPT. (/) #186. It was model #186 in the collection of the Patent Division of Burroughs Corporation. The machine is marked on the front: Burroughs Sensimatic.
Versions of the Series F were introduced in 1949, 1951, 1952, and 1954.
