Burroughs Class 3 Adding Machine

Description
This full keyboard printing manually operated adding machine has a metal frame painted black, a metal keyboard painted green, and seven columns of black and white color-coded plastic keys. A row of eight number wheels is visible at the front of the machine through a glass window. An operating handle that fits on the right side, and three function key stems are on the left. The printing mechanism, with space for ribbon and paper tape, is behind the keyboard. The carriage is 10 cm. (4”) wide, with a serrated edge for tearing the paper tape and a knob on the right to advance the paper. The machine is not entirely assembled and is incomplete. Several spare pieces are present, including a row of red plastic keys like the clearance keys on a Monroe.
The machine is marked on a tag at the front: 3-37428. It is marked behind the keyboard, with a “g” in an unusual font: Burroughs.
