Try Edmund Optics, they seem to have moved all their opticas to this area. They have some first surface listed on the web.

maxmanThe Edmonds Scientific site calls them first surface mirrors.
I think that is what they are called. Edmonds Scientific used to carry a couple of sizes too.

Since you live "just outside Atlanta", there must be a dozen or more glass & mirror shops in your phone book (that thing we used before the "net"). A few phone calls should find a shop that will special order it for you, and also cut it to size. Cutting any kind of mirror is almost an art - at least it is to me - so let the pro do it for you. If he breaks it it's his problem - not yours!!
