content: According to the donor, Charles S. Stones of St. Louis owned the instruments. From the early 1890s until the beginning of World War I, he used the set in his work building stairs. In order to get a building job in St. Louis at that time, Stones had to learn German. After the war, demand for showy stairways lapsed. Stones then used the instruments to draw house plans until about 1928.
