Toeknee, I would say he looks Cleveland, but there is just not enough of him to be a Purebred. Not a slam or anything, he is nice looking for sure. We have had two Rambler horses ourselves. He strongly resembles one, while our other has more of a chiseled head. He also looks CB, just not like yours.
Recognzing CB blood gets easier after seeing the first 10 or so, they are amazingly alike in the “CB look”. Nothing you can exactly finger, but CB look is there to see. Sure helps in spotting the part breds, whatever the cross, since few Purebreds are ever out to be seen. Pures are EASY to spot when you come across them, especially if they are mature animals. Proportion of body and mass are a big clue. All the parts go together very well, not clunky looking or moving, light-footed and agile, just massive but not drafty when you stand next to them.
We have spotted a number of part-breds when out in horse activities. We usually go and ask to make sure. Have seen Saddlebred, TB, Oldenburg, QH crosses. Have seen video of Morgan crosses. They all had “that look” to make them obvious to us, as CB crosses. Quite a number of non-registered ones, but the history that came with them said CB. Others who claimed CB lineage, didn’t look like it to us. Yup, just bay horses in larger sizes. No movement, or other characteristics to show the CB part.
CB breeds true because they are pretty prepotent with close breeding from those “almost lost the breed” times. A couple times there were only 4 Pure stallions in the WORLD!! The Sparks breeding program is designed to diversify the blood as much as possible, so inbreeding problems are less likely to happen. Heck, look at the QH, with all their numbers still have genetic problems! Two recent issues, HYPP and the HERTA skin are real visible with inbreeding just the last 15 years. Spreading into breeds allowing QH outcrosses, both are from QH based bloodlines.
People are impressed with the size and presence of the Part-bred Sporthorses. Can’t believe it can get better! They are overwhelmed when meeting the Pures. I think it is their eyes that make them all so appealing, kindly, interested appearing when looking at you. I know folks just appear from nowhere, when we take our Part-breds out in public. Some kind of universal appeal in them, brings folks right over to look closer. One mare always had a crowd around her stall, like she was a magnet. She is very gracious about it, accepting the attention. All her sons have it as well. Bred-in charisma. She is by Fryup Marvel, who is a real eye catching horse, gracious in accepting his attention too.
