BTW: Roy Rogers movies are shown on RFD TV. Trigger and Bullet are owned and shown around the country by the station.
Many Roy Rogers and other western actors are shown on Netflix instant play,and you can order the dvds for home viewing also. Right now Hopalong Cassidy, which was mostly for children, but a good role model, is available on instant play Netflix. My favorite westerns of that time period were Maverick and The Lawman.
