Worf,
that was taken at RAF Northolt, a place that I know 'rather well'!
In those enlightened days it was quite possible to ride up (on push-bike!) to the Main Gate and ask to take some photo's or the aeroplanes. The answer was almost always 'Yes'.
I will try to find a date for its visit. I seem to remember that it only pain one visit in this drab wishy-washy grey colour scheme, and by its next visit it had all been washed off.
