Art Nouveau Desk Lamp

I got this lamp last year, but never posted it because I wasn't sure of the shade, though I tried 4 different ones ( it didn't come with one). This is the one I like best so far. It has a very graceful design, and very nice detail, especially on the head I've never seen a lamp with this designe before. I just re-wired it and put in a new switch, It scared me a bit when I was using it, and when I opened it up, the wires were very old, and one of the wires on the switch just fell off. If anyone has a better idea of the shade that should be on it, please let me know.
Thanks for looking!
