I have just stumbled upon a site called "Urban Remains" but unfortunately for me they are based in Chicago. This site is paradise for all of you out there with a great interest in salvage and reclamation.
Whether you are searching for antique lighting, internal doors, stained glass panels or just curious this is the site for you. Highly recommended.
Some of the product categories you can search:
Historic Building Hardware
Vintage Builders' Hardware
Antique Period Light Fixtures
Antique Fireplaces and Mantles
Go on take a look you may find just what you were looking for.
