There is no other Concorde at Filton.
Current location of UK Concordes:
There were 3 UK prototypes; one at Yeovilton, one at Duxford, one at Brooklands.
There were 7 UK production Concordes as operated by BA; one still at Heathrow, one at Filton, one at Manchester, one at East Fortune, one in New York, one in Seattle, one in Barbados.
There was also a fatigue and temperature cycle test rig bare partial airframe at (I think) Farnborough. Bits of that are at Brooklands.
