I remain confused with Hoot Gibson's horses, as he had many in a career that spanned from the silents into the mid 1940s when he did the Monogram Trail Blazers.  Photos below show ol' Hoot on a half dozen different mounts --- there were several others.  The names of his hosses included Goldie, Midnight, Starlight, Mutt and Pal.  The story goes that the palomino 'Goldie' was killed during the filming of a chase scene ... or was injured during the filming of a movie, and had to be put away.

(Courtesy of Ed Phillips) Hoot Gibson - probably at Universal, circa 1927-28. This horse has a small white spot between the eyes. Is this Mutt or Midnight? (Courtesy of Ed Phillips) Above is Hoot riding Mutt or Midnight. It's difficult to see in this image, but this horse has a long white streak/face blaze. (Courtesy of Boyd Magers) Above are Hoot and his palomino Goldie in a scene from CONCENTRATIN' KID (Universal, 1930). The story goes that Goldie was killed during the filming of a chase scene ... or was injured during the filming of a movie, and had to be put down. (Courtesy of Boyd Magers) Above are Lina Basquette and Hoot atop the palamino Goldie in a scene from HARD HOMBRE (Allied, 1931). Goldie can be identified by a large white spot above/between the eyes. (Courtesy of Ed Phillips) Above are Gibson (on a white steed) and pretty June Gale in a photo from SWIFTY (Walter Futter/Diversion, 1935). Hoot is riding Jack Perrin's Starlight who could do all kinds of tricks including a bow. Check the Jack Perrin's Starlight section in Trusty Steeds to see a lot of western movie heroes ridin' this white horse. (Courtesy of Ed Phillips) Above from L-to-R are William Gould, Wally Wales/Hal Taliaferro (back to camera), Bob Kortman (on horse), Hoot Gibson on Jack Perrin's Starlight, George Hayes, and Lafe McKee in a still from Hoot's SWIFTY (Diversion, 1935). (From Old Corral collection) Above, the Monogram Trail Blazers, circa 1943-44.  From L-to-R are Ken Maynard (now riding the white Tarzan II), Bob Steele, and Hoot Gibson. The original Tarzan died about 1940. Gibson is riding Rusty, the Wonder Horse which had been ridden by Jack Randall and Tom Keene in their series at Monogram. When Maynard exited the Trail Blazers, Chief Thunder Cloud came in as the replacement - Thunder Cloud rode Rusty and Gibson rode a different mount. (Courtesy of Minard Coons) Above from L-to-R are Hoot Gibson on Rusty, Betty Miles atop her steed Sonny and Ken Maynard on Tarzan II in one of the early entries in Monogram's Trail Blazers series (prior to Bob Steele joining the group). (From Old Corral collection) Above is another of the Monogram Trail Blazer groupings: from L-to-R are Chief Thunder Cloud (Victor Daniels), Bob Steele and Hoot Gibson.  Note that Gibson is now riding a palomino with a long white face blaze.  And Chief Thunder Cloud is atop Rusty, the Wonder Horse.
