Burroughs Class 3 Adding Machine

This full keyboard printing manual adding machine has a metal frame painted black, a metal keyboard painted green, and nine columns of black and white color-coded plastic keys. A glass window at the front of the machine reveals nine number dials. A crank fits into the right side. Behind the keyboard is a 12” carriage with a narrow paper tape and a bell. The key tops for the five function keys are loose or missing.
The machine is marked on a metal tag attached to the front: #3-674863. It is marked behind the keyboard: Burroughs. There is a line through the “o” in this mark.
