Thanks Robbo.
That's definitely a Chance shape and I also have one of these dishes, where the gilt does overlap a smidge. The edge on mine's definitely wayward though – sometimes bevelled, sometimes flat!
So the overlap might not be significant then. I'm rather thankful in a way as I have a perfectly flat cake platter with three applied feet that must be the only item that's not slumped. Trouble is, the swirls are the 'wrong' direction and the spiral arms don't meet the edge. Grief, I wish I could find some consistency... pass the Valium, dear...
