I'll take your word for the history, but I'm still a little confused. The horizontal stab on the C+'s I've seen aren't at all the same as an A tail with a gurney, nor a B tail. They're much smaller, as is the vertical tail.
I didn't really mean to start a long thread, I was just curious about the full gurney along with the smaller size. What I don't know about aerodynamics would fill a very large book.
