Colton's horse was either Rex or Montrose Sea. Its name in the series was Joshua. in Incident in the Middle of Nowhere (1966), Colton says he and his horse had been through a lot together, including the Civil War.
Rod Serling was reportedly disappointed when the show failed in the TV ratings.
Lloyd Bridges' character was armed with an original M1860 Spencer carbine which was a very appropriate arm for the western period, but not the usual firearm of choice for any TV cowboy in those days. Bridges never fired his Spencer carbine although he did display it once in awhile to protect himself. The primary reason was due to the difficulty of the production company's armorer finding or making blanks of the long-obsolete .50 rim-fire cartridge the Spencer was chambered for. Reproductions of the Spencer carbine are now available in more modern calibers if they ever decide to bring back the show or add a bit more authenticity to another.
Colton's revolver is a 7.5 inch 1875 Remington that has some sort of homemade wooden grips. It is the metallic cartridge version of the 1858 Remington black powder cap and ball revolver. Despite the fact that he carries a cartridge revolver Colton carries no spare ammunition as he has no shell loops on his gun belt.
