notes: label: Description
content: This object was collected by Brooklyn high school teacher and historian of mathematics L. Leland Locke and held by the Museums of the Peaceful Arts in New York City before coming to the Smithsonian. It consists of a steel frame, shaft and gears with metal number wheels. Eighteen large number wheels are on the right, each with the numbers from 0 to 9. Ten smaller wheels are on the left, each carrying the numbers from 0 to 8 in white and then from 9 to 1 in red. The wing nuts at either end are used for zeroing, while a lever in front sets the decimal point. A bell is on the left side. Compare to calculating machine 309542 (a Brunsviga Midget).
