A brass silver-plated Bluebird 1928 model, created to commemorate Sir Malcolm Campbell's land speed record in the car, is to go under the hammer.
Auctioneers Bonhams said the model, which is 46cm long and 9.5cm high, will be among "automobilia" offered up at the Goodwood Festival of Speed sale on July 2 and could fetch between £30,000 and £35,000.
It represents the 950hp Napier engine Sir Malcolm drove while setting his 206.96mph record at Daytona Beach in February 1928, and was donated by his son Donald Campbell to their school - St Peter's in Seaford, East Sussex.
There is an engraving on the model which reads: "The Bluebird 1928, Presented to St Peter's School by Donald Campbell, In memory of his father Sir Malcolm Campbell MBE."
Between 1924 and 1935, Sir Malcolm smashed the land speed record nine times. In 1935, he became the first man to drive at over 300mph on land.
The motoring legend went on to break four water speed records, his highest speed on water was 141.74mph in 1939 in a Bluebird K4 on Coniston Water in the Lake District.
