Smart SCART multi-port connector (Kirkley NR33)

Very old tech - but this device from Blue Delta enabled up to four SCART devices to be connected at once to the TV. I used it years ago when I had multiple video recorders and DVD players etc but only one SCART slot in the TV. It's probably redundant technology now, as most modern devices don't use SCART to connect to the TV, but if anyone can use it that will save me taking it to the household recycling centre.
