For restoration parts for lamps, restoration services to rebuild or refurbish your beautiful antique lamp, or just browsing for antique and unusually beautiful lighting stock, Victor's is the one-stop lamp shop par excellent. They have antique, old, deadstock, and new parts built up over their years of business. I've been going to Victor's for years and years (they used to be in the SOMA district in the most untouched post-fire old OLD San Francisco building with the most amazing rickety clapboard floor I'd ever seen). Now that they're located just up the street from the big new Lowe's Hardware on Bayshore, they're even more convenient with easy parking. Why chase all over town looking for a rare lamp part, or even trying to find it on the web? Victor's will most likely be the source for itl. Fascinating shop to browse.
