the woman at the boot sale told me that the purpose of the machine threading on this jug was to provide a 'match striker', although the threading is much finer than on some other pieces I have with this type of decoration. Am I correct in saying 'mould blown (no seams anywhere), and the 'star' is cut rather than moulded. Despite the many water jugs I have seen this doesn't fit into the general run of shapes (most of which are larger) so I wonder if it was for some particular use. About 180mm tall, and there is a lot of wear on the base. Age wise, I am thinking something in the latter part of the C19. Does anyone else think the match striker idea is realistic, or is the threading perhaps more for decoration. Have to say I don't know whether to think this is British or not. Any opinions gratefully received, and thanks for looking.
