It might be worth checking to see if they bought any other chips for someone else. I know that's a lot of work, but if you have a bunch of this chip it might be worthwhile. For the Illinois clubs I've combined and cross referenced a lot of this stuff, but I can't help much with a California club.

I did a quick search for the address in the Taylor & Co business contacts file, since it has a lot of San Fransisco entries. Sorry, nothing there.
