Ron,
That is a beautiful bow.
I've had 5 of his bows, and a couple of A & H ones. All but one were ACS CX, and that remaining one was a 64", 52# fiberglass ACS limb T/D(exactly the same riser shape as yours). Mine has a different bolt pattern from his later T/D risers, and limbs are not interchangeable. However, some of the later risers will accept A & H limbs.
They are simply the best longbow and maybe the best bows I have shot in decades of collecting bows. Especially the carbon models.....which are definitely quicker. That's another subject, however. One thing I do know is my fiberglass ACS is as pretty as yours, a dream to shoot, and my belief is that it is more durable than a double-carbon limb.
