Andy - love the 'get my coat' line. Believe me, a wrong guess is fabulous. It's only by people being interested enough to have a go that keeps the ideas flowing IMHO. I always think a guess should be stated matter-of-factly too - just for sheer comedy value! :24:
Steven - of course it's related to yours - spot on - the rims could not be any more the same (perhaps the vase's worst feature? I think so).
Many kind thanks to you both!
