That might be true for latter day pipes but in the 17th and 18th century every clay pipe maker had his own personal mark which was put on the pipes. When digging in the Copenhagen underground the archaeologists found a good deal of clay pipes from said centuries and many were made by Copenhagen pipe makers and others were imported from Holland.
