G-AWSW is actually a 'non-EASA' aircraft. So it could prove a valuable asset to anyone wishing to buy it. You wouldn't need any EASA pilot licence and could quite happily fly it on a UK PPL for the foreseeable future whilst the rest of the UK struggles with the nonsense of pointless €urocracy.
It is also something of an historical aircraft, so deserves to be well looked after.
