Why am I an Automotive Masterpiece?

It appears to be the last chassis number (produced in 1937) of the 6C 2300 B Pescara (1st series)
The history of Alfa Romeo coincides basically with that of the history of the automobile and features many stories and numerous cars. The Alfa Romeo 6C stands out amongst the most representative models – the cars of the beginning and the modern post-war ones, and the racing and touring cars. The long journey of the Alfa Romeo 6C lasted almost 25 years, accompanying Alfa Romeo industries from the 20s to the 50s. In the early 1920s, Vittorio Jano was commissioned with creating a lightweight, high-performance vehicle to replace the large and heavy RL and RM models. Between 1927 and 1954, the Alfa Romeo 6C was produced in a series of models: road, race, and sports cars. The "6C" name refers to the number of cylinders of the car's straight six-cylinder engine. The different models’ bodyworks were made by coachbuilders such as Castagna, James Young, Pinin Farina, Touring and Zagato. From 1933, a custom-made Alfa Romeo’s built bodywork became available; it was made in Portello. The car was introduced in April 1925 at the Salone dell'Automobile di Milano as the 6C 1500. The 2-litre formula - that led Alfa Romeo to win the Automobile World Championship in 1925 - changed into the 1.5-litre formula for 1926’s races season. The production started in 1927, with the P2 Grand Prix car as a base model. The more performative 6C 1750 was introduced in 1929 in Rome. The car featured a top speed of 95 mph (153 km/h), a chassis designed to flex and bend over curved surfaces, as well as sensitive geared-up steering. It was produced in six series between 1929 and 1933. The base model had a single overhead camshaft. The Super Sport and Gran Sport versions had a double overhead camshaft (DOHC), and a compressor was available. Most of the cars were sold just as a chassis then bodied by coachbuilders. The 1750 quickly gained a reputation for winning races. In 1933, the last year of the 1750 production, the new Alfa Romeo 6C 1900 version was introduced, with a displacement of 1917 cm³ and with a light alloy head – used here for the first time. To satisfy the market’s request for a high-performance automobile sold at a lower price, Alfa Romeo introduced a new car at the Salone dell’Auto di Milano in 1934: the 6C 2300. The car was designed to replace the 6C 1750 and its derivate, the 6C 1900. Despite the many successes, the 8C 2300s remained designated for races and never appeared in the sales catalogues. The 6C 2300 debuted at the 1934 Giro Automobilistico d’Italia. However, only at the 24 Ore di Pescara, three Gran Turismo cars with bodyworks by Carrozzeria Touring won the first three places. Therefore, after the race, Alfa Romeo began to sell the model under the new name “Pescara”. The 6C 2300 was available as Turismo and Gran Turismo. The Gran Turismo version had better performances and also the reduction of the wheelbase (2920 mm). Except for the reduction in length, the chassis was identical to that of the Turismo model and was not distinguished by any particular technical innovations. Production was limited to 1934, and the chassis of all Gran Turismo versions were numbered from 700101 to 700635. A total of 1.606 specimens of 6C 2300 were produced, including bare chassis for the coachbuilders and complete cars. Alfa Romeo cars were absolute leaders in the history of the Mille Miglia race, and the various 6C models participated with actual squadrons, led by the most talented drivers of the time. The 6C 2300 participated in the Mille Miglia in four different years. Its debut was in 1935 when a specimen led by Franco Cortese earned the 8th place overall. At the 1936 Mille Miglia, three out of four participating 6C 2300s ranked 9th, 11th and 13th overall. Ercole Boratto, Mussolini's driver, drove the last one. The 6C 2300 were also the only ones registered, in that year, in the "Classe oltre 2.000 cc senza compressore" and, therefore, they were 1st, 2nd, 3rd in their class. In 1937, the 6C 2300 ran the Mille Miglia with 10 cars in their various versions. Ercole Boratto earned the best result in arriving 4th overall. In 1938, the 6C 2300 ran the Mille Miglia with 12 cars in their various versions. Franco Cortese earned the best result inarriving 9th overall.
The feature of the new 6C 2300 B was a highly sophisticated chassis. It was launched in 1935 and remained in production until 1938, and until 1939 for the Corto and Lungo models; it was then followed by the 6C 2500. It was embellished by four-wheel independent suspension, a rear swing axle and hydraulic brakes. Only the engine stayed almost identical to the preceding 6C 2300 model of the previous year, but nothing resembled the initial production. The new 6C 2300 B Mille Miglia was presented in 1937. The first Berlinetta Touring with Superleggera bodywork is chassis 813821 which ran the 1937 Mille Miglia with race number 119, placing 4th overall with Boratto-Guidotti: Alfa Romeo 6C 2300 MM Berlinetta touring Scuderia Ferrari. With a line aimed at aerodynamics, this berlinetta is to be considered a milestone in the history of Carrozzeria Touring, it is in fact the first "Superleggera" built; Touring patented the Superleggera design using ultralight alloys and components with aluminum panels over a cage-like steel frame: lightness is guaranteed, with a 6C body weight of only 126 kg. From now on, the Pescara berlinettas became the Mille Miglia with the new Superleggera bodywork. According to the registers, the Berlinetta Mille Miglia bodywork could also be fitted to chassis no. 813913, 813914, 813915, 813821, 813851. The 1937 cars would therefore be a few number of pre-series (or 1st series) Mille Miglia Berlinettas. The “regular” 6C 2300 B Mille Miglia (2nd series) was only produced in 1938, the numbering resuming in the range of chassis 815001 and 815101. The main difference is in the cockpit roof, higher in the 1st series and which will be lowered in the 2nd. It was the last of the series of 2300 B, based on the chassis of the 6C 2300 Pescara, with a 10 hp power increase, reaching the maximum speed of 170 kph.
Alfa Romeo 6C 2300 B Mille Miglia with chassis no. 813915 is one of the very few pre-series cars built in 1937 and still counted among the 6C 2300 B “Pescara”. According to the registers, no. 813915 appears to be the last chassis number (produced in 1937) of the 6C 2300 B Pescara (1st series). There is currently no news of the car's early years, but a sporting past, still to be investigated, cannot be ruled out. The car, found in Brazil, became part of the collectors' circuit in the 1980s and owned by Colin Crabbe. Restored in those years by the expert Fabio Calligaris, owner of the Atelier Fuoriserie, the car faced in the 2000s an intense career of participation in major events, such as the Mille Miglia and Targa Florio re-enactments. Noteworthy is the participation in the 1986 Mille Miglia, led by the well-known Colin Crabbe. The car got a Fiva pass and was counted in Registro Touring. In 2021 it was sold in a private sale by Finarte auction house.
