The one that just went for $162 looked a bit strange at the top lip of the lamp. It looked like it had a crimp in the metal, so this is why I did not throw down on it.
I love your Lucite disks, now I want to do the same thing to some of my lamps. Imitation is the highest form of flattery :-) Where can I acquire a couple of those bad boys?
