I caught a B-W episode the other morning when William Frawley played the part of Fred McMurry's dad. After Frawley's illness in 1965 the hard-working "substitute for mom" character later became uncle Charley, played by William Demarest.

The 21" BW TV that was showing a satellite launch the youngest was watching when he was supposed to be getting ready for school (year of US satellite launch in question), appeared to be a power tuned or remote set with the controls strip across the top, speaker board on bottom and likely a swivel base. Pretty sure it was remote but NOT a GE, Mag, Sylvania, Philco or Motorola.

Question: I think it was a Zenith but the name was probably blocked unless Zenith was a sponsor. I will look for pics of late 1950's SC models, but Id recognize the thin and simple control panel for sure.
