We believe it is Waterford (and have been told it is a rare piece) but would appreciate any information on the pattern. It has been suggested that rather than Waterford that it is from the Shannon factory, another maker of crystal ware in Ireland but we have no way to be sure. Please note the polished pontil on the bottom of the jug, a testament to its age. The height of the jug is 7 and it is 5 1/2 across widest point. The photos form part of the description so please examine them carefully.
