Solid state dual-wave stereogram.
Note: the logo on the right of the dial, appears to be similar to Thorn? This may be the tuning meter.
There is an earlier broadcast-band only 'Fiesta' model which looks quite different, Fiesta might have been a range of grams over a range of years?
Thanks to a helpful seller of an example of this model who was able to provide the chassis layout diagram above, the Fiesta has been matched to the schematics below and helps date the set to around 1968, although there is a reference to 'early sets' so it could have been 1 or 2 years earlier than this.
