I took this photograph on a visit to the Donington Park Museum in September 2014.
It's one of the two remaining very successful Austin 7 single seater racing cars that were built in 1935, and the board next to the car reads as follows:
'1935
Austin 7
Twin Cam
These
lovely little single seaters were Sir Herbert Austin’s reply
to the
successful M.G. Midgets fielded by Sir William Morris in
the
1930s.
Designed
by T. Murray-Jamieson, well known for his work on
super
chargers, and assisted by W.V. Appleby & T. Brown, the
cars had
a troubled debut in 1936, with most of the testing and
development
carried out here at Donington Park.
With
teething troubles rectified, these cars went from strength
to
strength during the 1937/38/39 seasons. Usually driven by
L.P.
Driscoll, C.L. Goodacre & “Bert” Hadley they competed in
everything
from speed trials and hill climbs through to 500 mile
races at
Brooklands. The two “twin cams” made many
appearances
at Donington Park winning, along with numerous
sprints
and handicap races, the Coronation Trophy here in 1937,
the
British Empire Trophy race here in 1938 and the Imperial
Trophy
at Crystal Palace in 1939.
Not only
were these cars pretty to look at, the 747cc
Engine
was an engineering masterpiece, very highly stressed
And
reputedly capable of revving to 12,000 R.P.M.'
I understand that this car is now at the British Motor Museum at Gaydon.
