What was Johnny Mack Brown's horse's name?

http://www.b-westerns.com/hoss-jm.htm says
Above, Johnny Mack Brown at full gallop on his palomino hoss during his series at Universal. As best I can determine, the hoss' original name was Reno, but was changed to Rebel when Johnny Mack was at Monogram in the 1940s. The reason for the name change --- his female co-star in several films at Monogram was Reno Blair (Reno Browne).
