Hammond Universal nº 7

Besides the curved two-row keyboard, which was finally rejected by the generalization of the model used still today, the typewriter also provided a universal QWERTY two-row keyboard.
The subsequent models, Nº 6, 7 and 8, created around 1896, are quite rare and were meant to be used in offices, businesses, naval and railroad companies, insurances and government institutions. Their main characteristic was to build wide trolleys of 16, 20 and 30 inches, respectively, and were ideal to work with tabulated tables, financial reports and statistical tables.
