Only a toy battleship. I think I've got ~ 7 or 8.
I swapped one for a green tricorn MDG bowl.
They do come in "Tiger" as well as with ribbons of coloured glass doused in silver chloride, some have crizzling, some don't. I do have an "Earthtones" one, in Boffo's hand, but I don't know if it's Mdina or MDG.
The ones with the silver chloride doused ribbons in them are basically the same construction as the big lollipops, just not all flattened out on the marver.
This is an image of my favourite one - the one I think is most like Roberta's.
And an image of the pawmark on the Ming globe (the one I think yours might be. Lots of loops followed by a squiggly long line)
(yes, they are a nightmare to try to capture on camera!)
