The aircraft is owned by The Fighter Collection, and although it's looking very complete, to say that the restoration is progressing at a slow pace is an understatement. Its been hampered by the fact that its engines are extremely rare (the specific type), and later versions of the same engines, which are more easily found, aren't compatible/can't be mounted.
Also at Duxford, a Bristol Blenheim is very close to flying again with ARCo, registered G-BPIV. It was seen getting some paint a couple of weeks ago (will have the early white/black undersides).
