The rumour about the spare tailplane was true.
I saw it in store at 30MU (Sealand) in the late 70s. I was intrigued as to what aircraft had a white, one piece wing (it appeared to be the size of the Hunter wing) so asked the suppliers what it was - nobody knew!
Got the Section/Ref and identified it from that.
On a job to Filton I saw the "twisted" fin and asked about that. The engineer I was working with said it had been twisted in an over enthusiastic missle avoidance trial!
