I might want it, but I don't and if the time frees up, I know where to get another one ;-)
Besides, I'm thinking this would be better suited to a steampunk project rather than a medieval one.
One end has a smaller hole than the other one, and it's really reqularly oval rather than chicken egg shaped, so cut long ways it could easily make two salt cellars of enormous size or cut in half the other way a pair of matched goblets of reasonable size, holding a little over a cup of liquid each.
