Search for pilot's family.
Squadron Leader Colin Hamilton MacFie took part in the Battle of Britain, survived being shot down and locked up as a prisoner of war and tried to escape a German camp.
Now the Spitfire he flew in, called St Helens, has been discovered in a French field by aviation enthusiasts.
Joss Leclercq, who led the excavation, said: "We know that he was a talented and dedicated fighter pilot, who was awarded the Distinguished Flying Cross, and he was very active in POW camps.
"But it would be lovely to fill in some of the gaps so we can build up a more complete picture of his life. I hope his family might be able to tell us whether he chose to fly in the St Helens Spitfire because he was from Merseyside."
The recovered Spitfire will go on display in a French museum later this year but restorers would like to hand over a piece of the plane to Sqn Ldr MacFie's family, if they can be found.
Sqn Ldr MacFie was born in Cheltenham in 1920, and moved to Liverpool as a child with his father.
