I have some A-based old cases made by H. Utendoerffer. Usually the name of manufacturer is attended by the name of the city - Nurnberg or Nürnberg. But one case has headstamp with Niernberg. As I know, Nürnberg is a traditional German name of the city. Also it’s English-style synonym Nuremberg existed. Who used name Niernberg? When and where this synonym of Nurnberg was used? Or, may be, this is only the mistake in headstamp?
