Yep, the Lincoln is the Napier owned aircraft that was displayed at Southend. Doug Arnold had a cache of parts from several Lancasters and the Lincoln stored outside the WoGB hangar at Biggin for a while, then the Lincoln ended up at Sandtoft and is now in Australia - or bits of it are... Some of the Lancaster bits are with Kermit Weeks, he has at least an entire airframe (the ex Charles Church/Strathallan G-BCOH damaged at Woodford), other parts also went to Oz for the Lincoln rebuild out there.
Very sad to think what wonderful flying collections we had 30/40 years ago which have scattered...
