This impressive mechanical office machine dates to the early 1900s and represents a fascinating piece of business and accounting history from the era before electronic calculators.
Features the original black finish, numbered keypad, hand crank operation, ribbon system, paper roll holder, and brass manufacturer plates.

The machine appears largely complete and displays beautifully. It has not been fully tested and is being sold as-is due to age. A fantastic conversation piece for an office, study, library, or collection.
