As mentioned above:
F K Mason's Hawker Hurricane - an Illustrated History, page 227:
Hurricane P3886 - No. 601 Sqn, Exeter, 10-40; damaged in landing accident, 15-10-40, but repaired; P/O J. W. Seddon unhurt. No. 1 Sqn, Kenley, 1-41.
Had it been re-serialed, it would have been noticed here. And further, would they send an instructional airframe to another operational Squadron? All that looks suspicious.
