I have corresponded several times this past week with a museum staff member in Nuremberg, Germany. He got excited about the sundial and has forwarded pictures to an expert on early scientific instruments and clocks in Nuremberg, who will know more about it. It will take at least a few days before I hear from that person. It seems the sundial is genuine, made about 1700 in Nuremberg by one of the town's best clockmakers, Johann Carl Landeck, who also designed and built astronomical instruments. But Landeck's work is rare, and no one in Germany has seen a small, hand-held pocket sundial by the man, so it will get more expert examination before I get a definitive answer. But so far, the news has been good, and the sundial has excited some people overseas.
