Vintage 'Addometer' in Carrying Case - 1950s discount - Instruction Sheets Included - Vintage Black Case - Dials - Adding Machine - Chicago

This is a vintage, 1950s 'Addometer' adding machine.

"This eight-wheeled stylus-operated adding machine has metal wheels and frame. The wheels each have ten holes around the edge. The two rightmost are white, the next three are red, and the discount next three are white. All the wheels are labeled around the outside with digits for use in subtraction and around the inside with digits for use in addition. A steel stylus and a clearing bar fit into the right side. The top edge of the instrument has an 11-inch scale of equal parts, divided to sixteenths of an inch. The machine was made by the Reliable Typewriter & Adding Machine Company of Chicago, Illinois." National Museum of American History

The fabric covered case is in rough condition and will not snap shut. The metal covering the dials is scratched and the screws are rusted. I have included all the paperwork, including instructions, but have no idea of it works.

Thanks for opening The Brown Suitcase!
