My source mentions 1899 for the photo of the so-called "express carriage", "Eilwagen". In 1900, 30 examples are said to have been built, payload 500 kg, engine power either 1.5 kW or 4 kW. In 1901, another three-wheeled front loader came onto the market, in the same year the company was sold to the "Nürnberger Express-Fahrradwerke".
Ludwig Loeb, the managing director, subsequently founded the "Ludwig Loeb & Co Automobilfabrik", brand name: LUC, later Dinos. In 1924, automobile production was discontinued; Ludwig Loeb took over the position of managing director at the AMBI-Budd car body factory in Berlin-Johannisthal in 1926.
