As the boys have said who knows what period the tile has come from as it was a very popular symbol everywhere, for example below is the Sydney Australia Customs house/Commonwealth Bank before they changed the floor. Someone has nicely recoloured this picture.

I also belive this item is original but probably from the 1890-1920. So it has not anything to do with the III Reich. Swastika is a very old symbol.
