And thank-you too, Bernard!
While I was up there, I checked my chains and fittings and found them to be of the same design as you describe- so I assume they are the originals too - something I didn't know before (although I suspected it).
Our shade has been in constant use since we bought it - many, many moons ago, from Alsretro's brick and mortar shop here and long before I knew anything about glass at all. It was just an instant "must have" for our home as soon as I laid eyes on it. Michael was less keen, the problem being "pink", but as soon as he saw how well it functions and how good it looks lit (a lot less pink!) he was won over.
I've even bought another (probably French) pink ceiling plafont with roses and a deco design since then, for another room, but it's not nearly as lovely as the Jobling.
Are you going to use yours?
