content: This model has two columns of white plastic keys and one column of green keys. Odd-numbered digit keys are concave, and even-numbered ones, flat. At the front, there are two aluminum numeral wheels on one shaft, and two on a second shaft in front of the first one. Two metal levers are on the right side, perhaps for zeroing. A shaft with a rubber handle is on the left side at the back. This is a study model of the supertotalizer motor-driven double register Comptometer. This form of Comptometer was invented by J. A. V. Turck. According to a label received with the collection, this model was built in 1943. It has no case.
