...I'm beginning to see how the setting register and accumulator work, at least. The helical shafts only transmit to the visible setting dials; the important shafts are the inner series of transmission shafts, where each setting lever shoves along one of those tiny five-toothed gears that provided the inspiration for the Curta logo. The strange multi-layered rotor with the elaborate pattern of teeth is what serves the role of the Odhner pinwheels, making each transmission shaft advance to a degree depending on the five-toothed gear's vertical position.
