That's XM603, another aircraft that was supposedly going to fly again, back in those days when people really didn't have a clue how difficult/expensive such a proposition really is.
Despite the external condition, 603 has had lots of attention from the people who look after her (ex Avro employees who built her in the first place), but I suspect their initial enthusiasm and devotion has slipped, now that the future of the entire airfield looks pretty insecure. Not much hope of an "Avro Flight Centre" with shelter for 603, when "Avro" will probably me moving out before too long, and leaving the Vulcan behind
