Burroughs Class 1 Adding Machine Section

This model consists of one column of a Burroughs Class 1 adding machine. Of nine key stems, seven have black plastic keys. The keyboard is covered with green felt. The frame of the machine is open and there is no glass. The key stems are bent, perhaps causing malfunction of the model. Part of a carriage, one set of printing types, and a wide ribbon are all behind the keys. A curious cylindrical device is on the left side. The model has a metal handle with a wooden knob. It can be displayed on a wooden stand, which has a steel support.
This is model #247 from the Patent Division of Burroughs Corporation. A metal tag attached to the object reads: DONATED TO (/) The Smithsonian Institution (/) by (/) Burroughs Corporation.
