His sire was a perfect red roan and the dam was a bay pinto overo Indian pony. I considered his breeding the very best. I (Gilbert H. Jones) had traded for Old Dunny Boy as a two year old; he was the best stallion I ever owned. He was a true buckskin, no stripes with a black mane and tail and a silver overlay. His mane was long and heavy and he had roan hair at the base of his tail, a big, bald face, glass (blue) eyes with dark eyelids, big mustache and pin ears that at times almost touched at the tips. Old Dunny Boy had a very small muzzle with very crescent nostrils and a heavy jaw. He had no chestnuts on his legs.
