Frosty, I mentioned the Jag as though the in service fleet had high hours, the RAFG fleet at Halton was low having been withdrawn about the time Bruggen shut, hence the "kit" could have been swopped over cheaply, I believe the RAF held Design Authority nr the end, but I could ne wrong, The wings on the Halton Jags eventually went to Oman to increase the fatigue lives on those.
