Stumbled on to this rarity recently. This is the first I have seen of this color in a Wizard. Jim tells me that Kirk happened to find I one too. I'd guess this must be one of the rarest Wizard colors going. As far as I know it is an undocumented production color or a production error. It is not a faded red colored lamp. The color is definitely factory applied and the inner edges of the lamp where the bottle sits are the same color. The bottle is a USA Pink/White.
Luckily the finish is scratch and dent free too as it looks like a new lamp.
