MACH5
Imperial Masterpiece
That's honestly one of my favorite things about this tree. I'll let Sergio answer for himself, but that lower branch is what I call a "conversation branch"... one that sets the tree apart from other similar trees and gets people talking about it.
I agree that the grafted second trunk is what gives this tree its value. For fun I am posting a photo of the tree before the branch was grafted.
