I have a 12" Griffin TV set in my collection. I guess the set was made in 1951  or 52 at the latest.

Griffin TV 1952

 

Thirty years later the Griffin name appeared on a TV set, an import from the far east.

Quite an uncommon make.

The logo on the newer TV looks like the welsh dragon ? Maybe a department store re-badge ?

That might be because it's a Gryphon.

Hi Frank, about five years ago Two Griffin DU11 TV sets turned up in Sunderland. Mine is a BBC only receiver and the other was converted to twelve channel reception with a Brayhead turret tuner.  The conversion involves removing the mixer valve and plugging in the converter leads into the mixer-oscillator valve socket. Actually it's not as simple as that, the converter plug carries an EF80 pentode. The IF signals from the tuner are injected into the circuit by connecting the co-ax lead to the EF80 valve's 150 ohm cathode bias resistor, the control grid is connected to ground. This arrangement provides a useful increase of gain but more importantly perfect matching to the IF amplifier is maintained.

 A topic about interlace problems with the two sets and how the addition of a frame sync pulse clipper circuit solved the problem: https://vintage-radio.net/forum/showthread.php?t=110096

No, the mythical dragon-like creature on the front is a Gryphon. You have heard of homonyms, I trust?

Jesus...

I quite like the look of the portable, is it 16" or 14" ? It has a scart so I guess it's mid eighties, do you know what chassis it has and does it work ?
