BTW I had posted this thread before, and it had some responses, and was curious to see it reappear without the former answers. Turns out this thread was a victim of the "print" glitch. FYI since I posted this thread, and a subsequent one, I have found that the only ready made frames extant for panoramics seem to be 8x20, and 12x36, but not easy to find.

What ultimately transpired was an account at a wholesale frame supply. They chop the moulding to my specification, and I assemble them. It has turned out to be very cost effective.
