TV show ran on CBS from 1955 to 1958. It was a radio show before that.
Somewhat odd format: The two stars appeared as Texas Rangers but in a different scenario each program. One week, they might be Rangers in the 1840s and the next week they would be current day Rangers, i.e., it was a history of the Texas Rangers.
from Four Color #961 (December 1958)
