Herod,
Heres your trusty steed (as found 4 years ago) you flew for the display in 1969.
The rest of the storage area was not a pretty sight and mainly bits and pieces of cannibalised Wx2.
However on the plus side, XR 505 was relatively complete, it was under engine and intake covers and apparently it is the airframe closest to full flying condition.
See photos attached. For the spotters yes, a H34 is sandwiched in the line as well.
I won't show you the rest, I hate to see/hear grown Wessexmen and women cry.
