1800 GMT Various including TOM MIX

In 1933, Ralston Purina obtained permission from western movie cowboy star Tom Mix to produce the radio series Tom Mix Ralston Straight Shooters, which, but for one year during World War II, was popular throughout most of the 1930s through the early 1950s, well after Mix's death. Mix never appeared on these broadcasts (his voice, damaged by a bullet to the throat and repeated broken noses, was not fit for radio) and was instead played by radio actors: Artells Dickson (early 1930s), Jack Holden (from 1937), Russell Thorsen (early 1940s) and Joe "Curley" Bradley (from 1944). Others in the supporting cast included George Gobel, Harold Peary and Willard Waterman. The Ralston company offered ads during the radio program for listeners to send in for a series of 12 special Ralston–Tom Mix comic books available only by writing the Ralston Company by mail. Most of Mix's radio work has been lost over the years; recordings of only approximately 30 scattered episodes, and no complete story arcs, survive. WIKIPEDIA
