That Hillbillies set looks a lot like the RCA roundie I have out back, the one I havn't identified yet.
It would make since that an ad man like Darrin would get a new tv every year, right? Probably had a tv company as a customer
I had been trying to i.d. their set before but never had quite a good enough shot. Other sets I can think of: on Happy Days they have a portable set brought in to the diner for some special event on tv. For some reason my memory from watching this as a kid says the set was color (which would be wrong, of course) but it seems that I've seen it again in recent years & it was bw. The album cover of Huey Lewis & the News "Sports" has a CTC31 (I think). Of course, there was the I Love Lucy episode where she pulls the guts out of the tv.
