He LOOKS like my gelding, Silky's Billy Joe. If he were 20, that would make him a 1997, and our stallion died in 1992. He could be a grandson, but you would need to be an APHA premium member(or whatever they call it) or an AllBreedPedigree member to look up all that prodigy....Our stallion was Silky McTavish, if you decide to go for it!
This photo was taken when he was QUITE young, as he mature, he had that long neck like your horse, and the huge wither....he always needed longer reins!
I don't break horses, I FIX them!
