The tape ends with another 30 minuter from the BBC, at a time when their programming was less bland that now.
(Thinks out loud!! "How nice these programmes would go on 'DAVE' instead of wall to wall Top Gear

The BBC ran a series called Perpetual Motion that looked at engineering icons such as the Route Master bus, the Morris minor car & 'The Old Grey Lady' https://www.youtube.com/watch?v=elENLa01XHA
Filmed during the last few months of the Shack's RAF service, when first transmitted it was unsure if any Mk 2 airframes would survive. History decided that, & God willing & with a wind straight down the runway it might not be too long till four RR Griffons are dragging and elderly old lady back into the air, (that's WR963 at Coventry BTW

Enjoy
(& I'll slip back into the shadows again
