The episodes I used were:
Flash Gordon (1954–55 live-action)
Steve Holland starred in a 1954–55 live-action television series which ran for 39 episodes. The first 26 episodes had the distinction of being filmed in West Berlin, Germany less than a decade after the end of World War II. This is notable, given that some episodes show the real-life destruction still evident in Germany several years after the war. The final 13 episodes were filmed in Marseille, France.
In this series, Flash, Dale (Irene Champlin) and Dr. Zarkov (Joseph Nash) worked for the Galactic Bureau of Investigation in the year 3203. The actual timeline was established in one episode, "Deadline at Noon", in which Flash, Dale and Dr. Zarkov went back in time to Berlin in the year 1953. The GBI agents traveled in the Skyflash and Skyflash II spaceships.
The series was syndicated, appearing on stations affiliated with the long-defunct DuMont Network, and many other independent stations in the United States.
