In addition to nine columns of black and white plastic keys, the machine has a repeat key on the right and a total key on the left. Nine numeral wheels are in front. The narrow carriage with paper tape is not visible from the front (e.g. not visible printing). The glass plate is missing from the front of the machine.

The Burroughs Style No. 1 adding machine (later called the Model No. 1) was manufactured with serial numbers less than 2254 from 1895 to 1908. In January 1905, the American Arithmometer Company took the name Burroughs Adding Machine Company. Hence this machine appears to date from about 1905.
