John:

You may be stuck with mail ordering from Willman-Bell - www.willbell.com. About 15 years ago there was a place in Oakland that carried mirror making supplies. It was called Optica b/c, but I don't know if its still around. Beware of using non optical grade abrasives such as those from a lapidary supply. They are not screened/filtered/graded as well as optical abrasives. I'd hate to see your mirror get screeeeeched by a stray 60grit rock floating in your 320!

Good luck,

Tom
