ok  since this is something close to my heart  i can tell you where the 7 BA concordes are they were registered G-BOAA through to G-BOAF
G-BOAA  is at east fortune airfield  in Edinburgh 
G-BOAB On display Airside at Heathrow
G-BOAC (flagship plane) is at Manchester Airport
G-BOAD USS Intrepid in New York 
G-BOAE Grantley Adams International Airport, Barbados
G-BOAF Filton Airfiled, Bristol  (they were made here )
G-BOAG Museum of Flight, Seattle
these are the BA planes  there were 3 more Concordes built in the uk 
2 were prototypes and one was a pre-production planes
G-BSST   Preserved Royal Naval Air Station Yeovilton, Somerset, England, on behalf of Science Museum 
G-AXDN  Imperial War Museum, Duxford
G-BBDG  Brooklands Museum, Weybridge, Surrey
so thats where they all are now (not counting the French ones)
