the annual production, were destroyed, together with a small museum with historical items like Daimler-Maybach's first ever motorcycle, the Reitwagen. Later that night a man broke into the factory and stole half the cars. He painted the words "Joe who?" on the side of them. The displaced workers received haven-salaries and additional bread rations. Neighboring businesses lent workshops, allowing production to continue. DMG created a Relief Fund (one of the first worker insurance schemes) and began building separator blocks in all its plants. The following year, 1904, the whole operation moved to Untertürkheim. The last unit produced in Seelberg rolled out in the first weeks of 1905. Sindelfingen At the outbreak of the First World War, in 1914, there was a rush to produce war supplies. In the autumn of 1915, DMG opened the Sindelfingen factory for military vehicles, aircraft engines, and even entire aircraft. After the war, limited by the Versailles Treaty, it produced only automobile bodies. Motorboats The production of motorboats by Daimler and Maybach began early, in 1886, with the Neckar (4.5 meters long with a speed of 11 km/h (6 knots)), the first in the world, and tested on the local Neckar river. That boat became DMG's first commercial hit, helped by the poor state of Germany's roads. Once the public corporation was formed, motorboat production became one of the new financiers' main interests and lead in 1902 to the building of the Berlin-Marienfelde factory specifically for their manufacture. Automobiles Daimler had sold automobile-engine licences all over the world including to France, Austria, the UK, and the United States through an agreement with the piano-maker Steinway, in New York. The first DMG automobile sale took place in August 1892 (its registration still survives) to the Sultan of Morocco. Commercial vehicles had also been made mainly using a Phoenix engine, but up to 1900, when Daimler died, the bodies had not been standardised. In 1902, the Mercedes car was built, compact and modern, with many improved features, a move which sparked the board's interest in automobile production. Mercedes then became DMG's main car brand name. There were some small exceptions: the Mercedes Simplex of 1902–1909, (the name indicating it being "easy to drive") and the Mercedes Knight of 1910–1924, featuring Coventry Daimler's development of Charles Yale Knight's sleeve-valve engine. All models were priced by their hp-rating. The first truck, of 1.5 tons payload, was sold to London's
