The number is for the design, which is called Carnival. Sometimes they are marked with the registration number as well 849118. Yours may be uranium glass, but the green isn't always. There is a sugar bowl, a milk jug, underplates, a biscuit barrel (sometimes wrongly sold as a vase without the lid), a vase, a butter dish, a cheese dish and the dessert set (6 small, one large bowl). I think that's it. Wayne has almost everything. I have the cheese dish and underplate on my site. Colours: blue, amber, green and clear. Clear is occasionally decorated.
