Total long shot, but I've always longed to see again the seasonal ident's used by Queen Margaret Drive for Christmas / New Year 1975/76 1976/1977 1977/1978 1978/ 1979.
I have seen the 1979/1980 version, which MUST be a contender for the Doctor Who Season 17 continuities VAM as it was shown before Part 1 of Horns Of Nimon on December 22, 1979. ( see screen shot below )
Previous versions used a form of "Spirograph" effect, or "Sutekh's" time tunnel overlaid onto the BBC1 Scotland mirror globe, as seen in my avatar.
A recreation of the "Sutekh" ident is on Youtube, made by the mighty Mike Pitt from my hazy memory!
Any screen shots or even Philips N1500 video clips would be most welcome!
