We try to keep a few fixtures in stock but that varies with orders. Since our products are custom pieces they are typically built after discussing the particular design with the client.
It's totally based on the size, material, detail and time for patina to "age". A basic medium size fixture will generally take about a 4 to 6 weeks. If the fixture has already been through the aging process then that time is significantly reduced.
Typically we do not, but if the fixture is an antique fixture that has a sentimental value to the client we will be happy to discuss further.
In most cases, yes.
