Burroughs Automatic Total Tax Machine, a Bookkeeping Machine

Description
This version of the Burroughs Class 7 bookkeeping machine was designed specifically for calculating taxes and payrolls. It has a gray metal case. At the front are two sets of digit keys, one gray and one white, as well as several function keys on the left. These keys are in two rows. To the left is a key mounted so that the stem moves horizontally.
Behind and above the digit keys is a space bar and four rows of a QWERTY typewriter keyboard. The “uppercase” symbols are not conventional. Behind the typewriter keyboard is a lever that can be set for any of seven registers. At the center behind the typing keys is a lever that can be set at “INACTIVE” or at any number from 9 to 15. Behind this is a wide carriage and a complex mechanism. The motor is under the machine.
The machine has no stand.
Marks on the front and the back read: Burroughs. A red tag attached to the machine reads: PATENT DEPT. (/) #203. A metal tag at the front of the machine has the serial number: A3857. This suggests a 1934 date. A mark on the gray plastic cover reads: Burroughs B. A mark on a white paper tag attached to the machine reads: For information (/) regarding this machine (/) see (/) H. Brown Room 587.
A card in the accession file indicates that this is a Style 72 07 22 machine.
