Allgemeinen Elektrizitäts-Gesellschaft (AEG) formed a subsidiary to make the Mignon typewriter called Union Schreibmaschine Gesellschaft (USG) aka Union Typewriter Company. This is not to be confused with the American Union Typewriter Company, which was actually a typewriter trust including multiple companys in the US in the 1890s. Apparently there are no known copies of the model 1 machine, so the earliest known manufactured was the model 2. AEG went on to produce up to model 4 into the 1930s.
