I know for a fact that Sears made Silvertones to at least as late as 1958.

...and as early as 1939.

I once trash-picked a Silvertone 18" color from 1967 (Japanese made, two-series string).
This was very early in my TV hobby (I was about 16), and I threw it back out when I could't get any B+ into it.
