Often listed as a German western, 30 Winchester for El Diablo is actually Italian. Carl Mohner plays El Diablo, a vicious bandit. He rules the roost until arrival of federal agent John Heston. The film's formal-sounding title indicates this may have been intended as part of a series. The original Italian title is 30 Winchester per El Diablo (wow--big difference!) ~ Hal Erickson, All Movie Guide
