What palomino did Roy Rogers ride in 85 movies before having him stuffed 1965?

Trigger was the name of Roy Rogers' famous golden palomino horse, who appeared with the cowboy star in 81 movies, not 85, during his career. Trigger was not actually stuffed after his death in 1965. Instead, he was buried at Rogers' ranch in Apple Valley, California, with a life-sized bronze statue of him erected nearby.
