The LHR example sitting by rwy23 is a permanent exhibit until the "final" position over at T5 is ready. Dont get any ideas, its bolted down!
The other is being dismantled in a hangar ready for transport by road & sea upto East Fortune (Scotland) later in the year.
Re the German Museum, Looking around I saw some more recent ones on planepictures.net showing both AF and Concordski standing in postion on plinths with gears down etc.
Very sad.
