When I first glanced at the pictures, I immediately thought of Shorty, my old (now-retired and raising another Pony Clubber on a free lease, lol) QH.
They could literally be twins, except Shorty was more "wild" bay, with a touch lighter body and slivery points.
I'd vote QH for sure...and it is honestly freaky how much they resemble each other! Conformation wise, he looks solid. He's definitely a keeper....Funny, too, how guys like this don't always look like much standing still, but can somehow moooove, lol. Although Shorty was notorious for the "pony trot" ;)
