I'm not blaming you for asking Jamie, there is a distinct possibility one is available here. I just know how difficult they are, I've been looking for the Cobalt top for years. I have the Peacock blue complete.
If I find a cobalt one will let you know..Years ago a friend of mine was selling at a bottle show and some one stole the top from his..so I guess that shows how hard they must be to find.[COBALT ONES} JAMIE
