Thomas,

I spotted this radio from an episode of the Rockford Files in a story about Russian spies.

According to IMDB, the episode, “A Material Difference” aired in February 1979.

Thanks so much for sharing this, Mark. You’ve got sharp eyes!

I remember watching The Rockford Files as a kid. I think it’s time to re-watch some of those episodes. Thanks again, Mark!
