Here is,based on osm, a hiking checkpoint for the EB hiking trail. Of type needler, I don't know what needler is but there is no such hiking checkpoint. Usually you get stamps either "official" ones with the EB logo or,especially outside Germany, generic tourism stamps. If someone can elaborate on that I would be very grateful.
