Description
This full-keyboard non-printing key-driven adding machine has twelve columns of plastic keys numbered from 1 to 9. The rightmost column has 10 and 11 keys at the top and 1/4, 1/2, and 3/4 keys below. Fourteen result wheels are at the front. A black cloth cover and numerous spare parts are present.
A red paper tag attached to the machine reads: PATENT DEPT. (/) #232. The machine is marked on the front: Burroughs (/) DETROIT, U.S.A.. A metal tag below the keys reads: 209662. A white paper tag attached to the machine reads: Reference Machine (/) 9 Columns (/) Style 520 - 1/4 Pence Const. (/) Style 13. A mark on the cover reads: BURROUGHS.
This was model 232 from the collection of the Patent Division of Burroughs Corporation. There are numerous associated parts.
The shape of the front of this instrument is that of an early Burroughs calculator. The number of columns would be that of a Burroughs model 550, although the tag refers to a Burroughs 520. From 1915, the shape of the front of the Burroughs calculator was quite different.
