I have a couple of images here that might be of limited help Glenn, I am currently out of town and only have access to the stuff I have stashed on my web server. Here is a picture that shows the braces of an old top although it's not a real good shot. The other is of my top pattern that was taken from this guitar. It is a concert model and the lower bout should be 13 1/2" so you may be able to take the pattern picture and scale it to your needs. I won't be home for about a month so I can't be of much help in the near term.
