Johnny Mack Brown is the one that is Branded A Coward in this B western produced by a Poverty Row studio called Supreme Pictures. It's not really his fault, he sustained a great emotional trauma as a child, seeing his family massacred by an outlaw only known as 'The Cat'. When he grew up he became a trick shot artist, but when it comes to gunplay with targets that shoot back, Brown can't forget.
But when he and sidekick Syd Saylor spot a stagecoach holdup they take a hand in and save the gold shipment and Billie Seward. A grateful town makes him their marshal which Brown decides to accept after he hears that it was the Cat's gang that did the robbery and is operating in that area.
This is one unusual B western in that it breaks one parameter of a B western which I will not tell and it has a surprise ending as to who the identity of the mysterious Cat is.
I'd check this Johnny Mack Brown western out.
