I had one of these long ago, before I learned who Warwick was. You may have a third color control, like Magnavox "chromatone" and its call "chromix" on a Sears IIRC.
Its a heavy set with a very sturdy plastic cabinet. Mine worked OK but did not look great, it was not the CRT either, but a borderline video or IF issue. I sold it for $20 to a kid who bought an Atari and he was thrilled.
I thought all the Silvertone color TV's were RCA knock offs
, mainly because they used many of the same tubes. The console Medalists looked like an RCA clone. The PC boards looked very different than RCA tho, almost like Admiral's did.
