There
will be a rare opportunity at this year’s Classic
Winton, Australia’s premier historic racing event, to
see the Maserati 250F driven by Sir Stirling Moss to an
historic victory in the 1956 Australian Grand Prix in
action on the Winton race track on 27-28 May 2006.
Following its display at this year’s Australian Grand
Prix, marking the 50th anniversary win, owner and driver
Peter Giddings has kept the car in Australia
specifically to take part in the Winton event. Far from
a museum piece, Maserati 250F chassis number 2501 is a
regularly used and, as ever, it will be driven hard at
Winton, enabling spectators what has made the 250F a
legend.
“I have
done more miles in this car over the past 30 years than
Maserati ever did,” explains Mr Giddings. “In fact, I
have worn it out three times, as we have carried out a
complete restoration of the car three times to keep it
in perfect racing condition. It looks, sounds and goes
now exactly as it did when Sir Stirling Moss took the
chequered flag 50 years ago in Albert Park and I looking
forward to putting it through its paces at Winton in
this excellent event.”
The Winton Classic will take place
the Winton raceway, which is 200 km north of Melbourne,
on the weekend of 27-28 May 2006.
MASERATI 250F CHASSIS NUMBER 2501
The
first public appearance of Maserati 250F (#2501) was in
October 1954 at the Paris Salon. #2501 was whisked off
of the stand during the evening prior to the last day,
and was driven at the Spanish Grand Prix (Barcelona) by
Stirling Moss. #2501 was fitted with the first of the
new non louvered 1955 body design, setting a pattern for
the car throughout its factory team car life. Thus
practically on each and every appearance from 1954 to
1957, #2501 incorporated factory updates.
During
its factory team career, #2501 was driven by Fangio,
Musso, Mantovani, Godia Sales, Moss, Perdisa, Villoresi,
Behra, Bonnier, Menditeguy, and Scarlatti, with podiums
by Musso (Bordeaux, Naples, Syracuse, and the Dutch GP),
Behra (Rheims). Moss (now Sir Stirling Moss) achieved an
outstanding podium place in the German Grand Prix,
followed by the memorable first overall in the 1956
Australian Grand Prix.
Upon the
dissolution of the Maserati racing team at the end of
1957, #2501 was rebuilt as new, renumbered as #2523, and
sold to the only female Grand Prix driver of the time,
Maria Teresa de Filippis. Subsequent to de Filippis'
appearances at the Syracuse, Monaco, Belgian, French,
Portuguese, and Italian Grand Prix, #2501 (#2523) was
once again campaigned by Scarlatti. Subsequently, #2501
(#2523) ended up in the hands of New Zealander, Brian
Prescott (via Ross Jenen). Extensively campaigned
during the 1961 - 1962 seasons, Prescott achieved three
first places at Levin in April 1961. Via Leon Witte of
New Zealand, #2501 (#2523) ended up with Cameron Millar
in the U.K., who completely restored the car and fitted
the engine #2522.
Engine #2522
achieved first places at Goodwood and the Monaco Grand Prix,
together with a third place at the Belgian Grand Prix in
1956 driven by Stirling Moss, a second place at the 1957 Pau
GP driven by Harry Schell, and a third place at the 1960
Buenos Aires Grand Prix driven by Munaron. Campaigned
extensively in historic racing by Millar, Christopher Mann,
and Keith Duly, Peter Giddings acquired #2501 (#2523) in
1986, and has since chalked up over 18 wins and many podium
placings in events throughout the USA, Canada, New Zealand,
and Australia.
