I believe it is the only Attacker.
The FAAM also have the sole surviving Hawker P.1052 left in existance (3rd row, extreme left of spey111’s first post).
Hopefully one day there will be enough time, space and money to put the aircraft back together.
The Fleet Air Arm Museum preserved Humphrey, a Wessex HAS.3, after its exploits in the Falklands.
One of their Westland Wasps may also have some history from the conflict.
