"The designer of this machine is Chr. Hamann, Berlin. Figure 318 shows the first model, which was driven manually. In both the interests of expediency, and to comply with what has proven popular with the machine operators. the designer has provided the machine with the same exterior design as that of the Odhner machines and also copied its dimensions. The interior design of the machine, however. is completely new and original and has nothing in common with the mechanical principles of the Odhner models. Its most important working part is not the pinwheel itself but a geared wheel with a thirty-six-part inner and outer gearing (see figure 319)."
