A 1948 Alfa Romeo 6C 2500S Pinin Farina cabriolet is among the highlights of Silverstone Auctions' November 16 sale.
The lot will cross the block at the famous Silverstone racetrack in Warwickshire, UK with a valuation of £225,000-275,000 ($362,839-443,470).
Writer Andrew Newton explained the origin of the model in a 2012 edition of Sports Cars Digest.
"Like so many of the great names in the automotive industry in Continental Europe, Alfa Romeo could not escape from the grim political and economic realities surrounding the Second World War," he said.
"The company was technically controlled by the Mussolini government from 1932, and the factory fell victim to Allied bombing during the war.
"Alfa struggled in the immediate postwar years to find a proper niche for itself in terms of road car production.
"The bigger, grander, more elegant sports cars that they had built before the war would not see to the company's long-term success, so the construction of smaller and cheaper but still high-quality sporting cars was pursued.
"This shift in Alfa Romeo's focus worked, and they built some of the most memorable cars of the 1960s and 1970s."
The present lot was sold in Turin in 1949.
Years later, it ended up in Chile, from where it was procured by the consignor, shipped to Australia and housed in a museum.
The record for an Alfa Romeo stands at £5.9m ($9.4m), set for a 1935 Tipo 8C-35 racing car at Bonhams last year.
