Model SW1-S15/2NG and proclaimed itself to be a 15" LCD TV RECEIVER.
This has in the past been used to receive TV via it's RF input socket but whether there's anything being broadcast for this older technology, I can't say. More usefully it can be used as a monitor for a computer or CCTV system or maybe a games console, featuring SCART and VGA inputs, S-video, audio and RCA.
If this is of use to you then it can be collected from Matlock.
