Indeed the title of the programme concerned was Perpetual Motion, I’ve a digital copy of this, but it was converted from VCR and not all of it made the conversion.

WL798 was still substantially complete whilst I was at Lossie for a week long visit to 8 Sqn in Jan 1990. However, 3 months later I do believe WL738 (the gate guard) and WL798 got the chop, moving to Williamsons scrapyard in Elgin.

The programme IIRC does not focus on WL756, all filming of the Shack in the programme was at Lossie, no sign of St. Mawgan I think.

I have seen reports of WL798’s nose surviving, but to be honest, if you see the way it is getting hacked to death by a JCB in Perpetual Motion, I don’t think there was any attempt at salvage at all.

Hope this helps,
Scotty
