Never noticed the tank, but I think it may be a spare they had lying around at the museum. I'm not claiming any knowledge on the subject, but it may be off the Meteor they have there. The 111 Scheme is obviously unfinished. The museum is only open at certain times, so I couldn't get any info, as there was no one there to ask. It may be the angle I took the 2 pics at, but the thing that struck me when comparing it with the old pic of the 64 Sqn markings was the similarity between the 2 versions of the Tornado. The black nose on the 111 marked pic appears to make it look more squat than the grey 64 pic, which has a sleeker looking effect, similar to the difference between a camo GR1 and a grey F3 Tornado.
