118 Sqn Vampire T.11 taken from the Meteor in the previous shot - before 29Apr54.   The under wing drop tanks confirms this as a Vampire T.11 and not a Venom.   Probably Vampire T.11 WZ517 Z which arrived on 118 Sqn on Thu 29Oct53 and was sent back to Marshall's of Cambridge on Mon 18Feb57 for modifications.    (Thanks to Mike Wraight.)
