Slight digression, but wasn't a Vulcan used in the development of the RB199
for Tornado? Carried in a 'pod' underneath that was a replica of the
proposed air intake solution?

Wouldn't surprise me, it was also used as Pegasus test bed. Wasn't one
Vulcan testbed damaged when an engine for TSR2 exploded on the ground?
