Haven't seen the movie, but sounds like one of those early would be Ringos indeed
Funny thing: according to Marco Giusti Gordon Mitchell's character is called Ringo (or better: was renamed Ringo, originally he was apparently called Baltimore Joe), while Rod Dana's character is called Jerry Colt (it takes to Italian to invent such a name!)
The film was launched with the slogan (the last one of the article): La leggendaria storia di Jerry Colt, l'uomo che uccise Ringo" (The legendary story of Jerry Colt, the man who killed Ringo)
Is Dana in the English version really called Ringo?
Wouldn't surprise me, by the way
