The couple said they were using a special mix to restore the leather seats – one they had developed just for Concorde.
Mrs Hutchins said: “We are really lucky to do what we do and work on some amazing items.
“We’ve had lots of things in from all over the world, but to work on something that has travelled all over the world is just really humbling.”
She added the first exciting moment came when they were removing the seats and found items people had lost down the side, including chocolate from New York.
Mr Hutchins added it felt “so special”.
“This particular Concorde was used by the late Queen and the royal family. It’s the only one they ever did use,” he said.
“For us, we are preserving history and the heritage for the country.”
