A replica of one of the earliest Bluebird crafts used by Malcolm and Donald Campbell has gone on show.
The K4 broke the world speed record in 1939
The Bluebird K4 is being exhibited at the Lakeland Motor Museum at Holker Hall at Grange-over-Sands in Cumbria.
It joins replicas of two other Bluebirds, including the K7, in which Donald Campbell was killed in 1967.
The K4 was piloted at Coniston Water in 1939 when Sir Malcolm Campbell raised the world water speed record to just over 141 mph.
In 1950, his son Donald took the craft to 152 mph.
But while reaching speeds of around 170mph on Coniston Water, the vessel suffered a structural failure and sank. After salvage it was stripped and burned.
Don Sidebottom, who founded the museum 26 years ago, said: "Our objective is to keep the Campbell Bluebird heritage alive and we have been extremely fortunate in being able to secure the K4 replica for public display.
"It is particularly important given its Lake District connection and our close proximity to Coniston Water, where Sir Malcolm and Donald achieved so much for Great Britain".
In March the wreckage of the tragic K7 Bluebird was sold to the Ruskin Museum in Coniston for just £1.
It was raised from the bottom of Coniston Water in March 2001, where it had lain for 34 years.
