Hi!
Here is an addictive website that simply must be perused: antiquelight.com. Please click on "Antique Lighting and Lights" link in the center of the home page, about 1/3 of the way down.
Thanks!
An Utterly Amazing Site of REAL Victorian Light Fixtures
Yes, I've been to that one before. Amazing stuff and the prices are appropriately up there due to the quality and rarity.
