content: In 1927 officials at Felt & Tarrant Manufacturing Company of Chicago learned that rival Burroughs Adding Machine Company of Detroit had one of its recent machines on exhibit at the U.S. National Museum (as the Smithsonian’s museum was then called). They offered to supply the museum with an example of their latest adding machine, the Model J Comptometer, and to construct a section of the device for display. The museum accepted the offer, and received both a Comptometer and this model.

content: The section has three columns of keys with yellow (two right columns) and green keys. Complementary digits are indicated on the keys. There also is one red key. Two numeral wheels are at the front, and a zeroing crank with wooden handle is on the side. Part of the top is steel, painted brown, and the rest of the casing is glass and allows one to see the mechanism from the sides. The mechanism is metal. A bell rings when the dials are cleared. Four rubber feet are screwed in place.
