I was at Cosford today, and had a look at 818. There don't appear to be any multiple rows of rivets, and if I can I'll post a couple of photos. From what I can gather, the wings were removed when it was transported to Cosford, but this was just a case of dismantling and reassembling. No cutting involved. BTW, she still looks a pretty aeroplane.
Sorry, can't post pictures at the moment. Will try later.
