This full keyboard printing adding machine is manually operated. It has a metal frame painted black, with a metal keyboard painted green. There are five columns of black and white color-coded plastic keys. The non-add, total, and subtotal keys are on the left. The repeat key is on the right. In front of the keys is a row of six number dials, under glass. These indicate the sum of numbers added. The crank on the right side operates the machine.
Behind the keyboard is the black ribbon, printing mechanism, narrow carriage, and paper tape. The tape is visible to the operator, unlike that on earlier Burroughs machines. There are six digit type bars with an additional type bar right of these that prints symbols.
The machine is marked on the back of the keyboard, with a line drawn through the letter “O”: BURROUGHS. It is marked on a metal tag at the base of the front: 3-283826. It is marked on the back (partly obscured): BURROUGHS ADDING MACHINE CO.
Compare MA*323588. Burroughs acquired the Pike Adding Machine Company of Orange, New Jersey, in 1909. This machine is very similar to the Pike.
