Looks like the same form..first one I have seen mounted that's a big bull!
It's an Ak/Youkon bull from a few years ago. If I remember right it's a Shiras form so we, or I should sayTodd Peyser, had to do a lot of mods on the head...lengthen/widen/extend the jaw, nose, head and neck.
That's a great bull you've got, should look really impressive at eye level.
