Colin, as far as I remember, the only main issue would be the integrity of the main spar. As NX611 is a late-production MkVII, there's a very good chance that the spar will be in good order, and pass the CAA requirements. The downside is, NX611, if it gets airborne, might take over the mantle of the only Lanc flying in Europe, if the British Government have their way, and 'scrap' the BBMF !!
