Edinburgh and Waterford both contract out. Waterford calls that stuff Marquise (or is Marquise the genuine Waterford stuff? it's got a waterhorse logo)
Edinburgh also does, but not for its signature patterns of Iona, Star of Edinburgh and the Thistle one.
I was referring more to things like the importer LSA, and these new companies - like Glencairn - (and perhaps this one, Caledonia) which might well be all made elsewhere and just imported under a Scottish sounding name.
Not to older, more established companies contracting out.
