notes: label: Description
content: This billing machine is an example of the type introduced by Burroughs Adding Machine Company in 1922. The large, printing, electric machine has a metal frame painted black and dark green. Two rows of keys, which have two sets of digit keys on them, are at the front, and control the computing mechanism. One set is used to set up amounts entered into the registers and the other to actuate the multiplier.
label: Description
content: Behind these rows of keys are four rows of typewriter keys, used to type text. The letters are arranged as on a QWERTY keyboard, but all letters are typed in uppercase and the second symbols indicated on some keys are quite different from a conventional keyboard. All of the keys are covered with what appears to be rubber. A lever on the right above the keyboard can be set for any of three registers. The wide carriage is above and behind the keyboards, and further mechanism behind it.

content: The red and black ribbon would be enclosed if the case had all its side panels. The machine lacks a stand, but has a motor below. Loose in the case is a flat metal piece and two pieces that fit across the carriage, as well as six smaller pieces – one is a plastic button and five others are metal screws and tacks.
label: Description
