They do things bigger on the west coast. Liz's Antique Hardware is a great resource for just the type of vintage hardware that New York apartments love. With a collection of more than a million pieces of salvaged hardware (circa 1850 to 1970), LA has hardware for doors, windows and furniture. They also carry lighting, bath accessories, and "other things that catch our eye."
Prices run from $6 for a doorstop to $12,000 for an art deco ceiling lighting fixture, and everything is orderable online. Of course, they don't have everything online, but they have a good amount and it is very nicely laid out so you can find things quickly. MGR
