The History of the "Aussie" Alfa Romeo
The history of the last remaining Alfa Romeo G1 is as colourful as the company that give birth it. Chassis 6018 was imported new into Australia in 1921 and was sold, for #850, to a Queensland businessman who, soon afterwards, was declared bankrupt.
Since he had seen his financial crash coming, he hid the car to keep it out of the hands of his creditors.Then, three years on, he had the misfortune to die and the G1 remained hidden for 25 years, apparently holding up one corner of a shed in the Queensland outback.
Then it was discovered by a couple of young jackaroos who decided it would make a fine 'paddock bomb' for rounding up cattle, chasing kangaroos and all the stuff that blokes do on farms. Eventually they managed to hit a tree and the damaged car was towed back to the farm where it was used to power a water pump. With its massive torque at low engine speed, it was ideal for the job and the work ensured that the engine remained in excellent condition even if the rest of the car was brutalised.
In 1964 it was retired from pump duty and rescued by Alfa Romeo enthusiasts. The following year the car was bought by Ross Flewell-Smith who, against the advice of some experts who thought the car unrestorable, began to rebuild it, an exercise that took ten years. In this Herculean task he was helped by the fact that he discovered a second G1, a wreck, which supplied many of the parts that were missing. Most of the body was missing and, after experimenting with various styles, Flewell-Smith took advice from Luigi Fusi who was then curator of Alfa Romeo's museum.
Flewell-Sinith's rebuild was good enough to win the 1977 Queensland Vintage Car Concours and to win the 1978 Australian Mile Miglia memorial run. In an historic race at Lakeside it was clocked at 86 mph, remarkable performance for a 1921 car, so remarkable, in fact, it was black-flagged for being so quick!
In 1995, Flewell-Smith sold this car he had nicknamed 'Milly' from the 'Milan' on the engine black, to Julian Sterling who commissioned a restoration to his own exacting standards. All worn parts were replaced with specially-made components built regardless of cost. New tyres were supplied by Michelin, made from the original 1920s moulds, costing $6,000 for the set. The restoration was undertaken up to a standard, not down to a price, and the work was described in the 1998 edition of the Classic Car Yearbook as 'breathtaking'.
Following a rationalization of Julian Sterling's car collection, the car was bought by Neville Crichton, the governing director of the new Australian Alfa Romeo importer, Ateco Automotive Pty Ltd.
Following his purchase of the Alfa Romeo G1, Neville Crichton undertook a full restoration of the G1 to return it to full running order. The quality of this restoration was rewarded in 2005 when the car was entered under stewardship of Australia's leading classic car journalist, David Berthon, in the World's most important classic car event, the Pebble Beach Concours d'Elgance and the Third in Class Trophy, beating more than 60 classic Alfa Romeos from around the world, including seven cars entered by Alfa Romeo's own museum.
