Burroughs Adding Machine

Burroughs Adding Machine

Description
This full-keyboard printing electric adding machine has a dark brown metal case and square plastic key covers. An operating bar is on the right, next to a column of function keys, and a column of 1/8 to 7/8 fraction keys. The next two columns contain a total of 15 keys, numbered from 1 to 15. There are then seven columns of digit keys, with nine keys in each column. The narrow carriage at the top of the machine has a serrated edge for tearing the paper tape. The paper tape, paper tape holder, and handle are separate.
The machine is marked on the front: Burroughs. A red tag attached to it reads: PATENT DEPT. (/) #281. A metal tag attached at the lower front reads: D3555.
