Hi MalibuSam,
Unlike the thread for your egg shaped item, I have not added an "ID =" comment to the title of this thread as Alan's suggestion was just that - a suggestion. He could be spot on, but it does need to be looked into to ensure that the ID is correct.
In response to Sue's comment about the "mystery PK"mark, that is something that applies to a range of glass items that fall under the general "Bohemain" category. But I do not think it applies to any paperweights or mushroom style items.
