Stima Adding machine

This handheld instrument has nine parallel brass rods with holes in them. The holes in each rod are numbered from 1 to 9. Numbers are entered by pulling down rods with a stylus. The total appears in a set of nine holes at the bottom of the instrument. A lever on the side may be set so that a number entered is recorded in another set of nine holes that are immediately below the columns. The machine also has a carry mechanism; a white plastic zeroing button that is pulled out to zero the result register; a brown plastic button that is pushed to zero the entry register; a white plastic button used for subtraction; and decimal markers. Instructions are stored with the object and its leather-covered velvet-lined case. The stylus is missing.
