Hello, Henniger, founded in 1824, was one of the first European makers of holloware and flatware from "German silver" (also known as Alpakka, Alpacca, Packfong, Alfenide etc.), an alloy which does not contain any silver, but looks like silver. Henniger changed ownership several times, the production line for holloware went to the Juerst company from Berlin, last known owner of the flatware production line was a Hermann Zielke from Berlin, who aquired it around 1910/1920 and continued to use the name of Henniger as a mark. I would date your pieces, very roughly, around 1900/1920. It is not known when production of Henniger flatware ceased, probably in the 1930ies. Henniger originally also ran a chain of stores where the company sold its stuff and stuff from other makers. Stores were in Berlin, Breslau, Hamburg, Leipzig, Dresden among others. Last existing store was in Leipzig, which after the foundation of communist East Germany moved to democratic West Germany. Who knows, maybe it still exists ? As to the meaning of the "60", see here
