Mack wants me to tell you he says you are looking at what is commonly called a "Dink" in this area:)
Of the 3 Okie has the most look of old foundation QH. Short and wide. Harley, IMO, is a little to lanky to have classic QH confirmation, but he has alot of good points to my taste. I like big butts:) and small heads.
Did the site give any of his/her bloodlines? That can tell you alot?

If you go straight up the crease between Okies belly and hip, his hip starts almost exactly in the middle of the white strip with the edge of the bone on the crease line.
