The trophy, a model of the single-step hydroplane Bluebird K3, has attracted a pre-sale price of more than £35,000

The trophy presented to Sir Malcolm Campbell on breaking his first world water speed record is to be auctioned off next month.

The trophy, a model of the single-step hydroplane Bluebird K3 in which Campbell set the record, was awarded to the legendary English record breaker upon hitting the new world record speed of 126.33mph on Lake Maggiore in Switzerland on 1 September 1937.

It has attracted a pre-sale price of £35,000 to £50,000 ahead of the Bonhams auction on 24 March.

Campbell broke nine land speed records between 1924 and 1935, and was the first man to exceed 300mph on land in 1935.

He went on to break four water speed records; his highest speed on water was 141.74mph in 1939 in Bluebird K4 on Coniston Water.
