Reel Cowboys of the Santa Susanas -- Grant Withers

Grant Withers (1904 - 1959) was an American film actor.  During his career he did manage a 10-year contract at Republic Pictures. 

His friendships with both John Ford and John Wayne secured him a spot in nine of Wayne's films, but later roles dwindled to supporting parts, mainly as villains in B-movies, serials, and finally television.
