After a weekend of digging around, I found both the video and the tv series on video, and a little bit more research also realised it was WL798 that was scrapped at Lossie in early 1991, and not 801 which went back to 2 SoTT at Cosford after 8 finished with it. It even had a spell with the Aerospace museum, before 2 SoTT got it back and it was disposed of.
