The working titles of this film were Shotgun Messenger and Ghost Town Buckaroo. While the onscreen credits state that the screenplay was based on the original story "Shotgun Messenger" by Arthur St. Claire, a memo from Universal to the AMPAS library stated that the story was unpublished and that the author had retained the right to publish it at a later date. The actual character names for actors Harry Tenbrook and "Blackie" Whiteford were unreadable on the viewed print, while contemporary reviews list them as "henchmen." Actor Henry Hall's character was misidentified as "MacSwain" by CBCS. Modern sources include Kermit Maynard, Frank Ellis, Hank Bell, Ray Jones, Jim Corey, William Nestell, Carl Sepulveda and The Guardsmen Quartet in the cast.
