Arguably the biggest name in global motor sport, Scuderia Ferrari entered its first race - the Mille Miglia - in 1930, running a team of three Alfa Romeos. One of its drivers was the gentleman racer, Luigi Scarfiotti, who drove the car offered here, chassis number '8513033'. The latter was one of the first cars ordered by Scuderia Ferrari late in 1929, and was registered on 1st April 1930 with the Macerata registration, 'MC 2012'. A plaque bearing the legend 'Concessionaria Emilia Romagna-Marche - Cav. Enzo Ferrari - Scuderia Ferrari' is fixed to the dashboard. 

Some 40 years later, Scarfiotti would recall that the Carrozzeria Zagato had been commissioned to construct a lightweight body for the Mille Miglia. Scarfiotti's choice of car echoed that of his political master and Italy's leader, Benito Mussolini, who was the proud owner of a Zagato-bodied 6C 1750SS. Marque authority Angela Cherrett quotes production figures of between 206 and 213 cars for the combined 4th and 5th Series 6C 1500 and 6C 1750 Gran Sport.

Less than two weeks after taking delivery of his new Alfa, Scarfiotti drove it in the Mille Miglia. The Alfa Romeo 6C 1750s dominated that year's event: Tazio Nuvolari winning outright while the 6C 1500 won its class. Sadly, none of the Scuderia Ferrari cars finished, Scarfiotti's being eliminated by a broken suspension leaf spring. Scarfiotti continued to campaign his Alfa, finishing 2nd overall and winning his class at the Colle di Paterno in July, and contesting the Circuito di Senigallia the following month (he failed to finish). By the season's end Scarfiotti had finished 5th overall in the Coppa Gran Sasso, 4th in the 12-mile Teramo-Civitella del Tronto hillclimb, and 4th overall in the Coppa Pierazzi. 

Having enjoyed a fair measure of success in 1930, Scarfiotti was ready to make another attempt at the Mille Miglia with his Alfa in 1931, again running as part of Scuderia Ferrari and carrying competitor number '117'. On this occasion fortune would smile on Scarfiotti, who finished 6th overall, 1 hour 17 minutes behind Rudi Caracciola's winning Mercedes SSK. Remarkably, Scarfiotti's 6C 1750 GS came home three places and 21 minutes ahead of the highly favoured new Alfa Romeo 8C 2300 driven by Nuvolari. Attached to the car until recently, the scrutineer's lead seal stamped '1931' and '117' is included in the sale. Scarfiotti's performance led to an invitation to drive one of Scuderia Ferrari's Alfa Romeo 6C 1750s in the 1932 Mille Miglia. Partnered by Guido d'Ippolito, Scarfiotti finished 3rd overall. 

That same year Scarfiotti sold '8513033' back to Alfa Romeo. The car was registered to the Alfa Romeo Company, Milan on 18th May 1932 with the number 'MI 38883'. In 1935, possibly having suffered a mechanical failure or some other damage, the Alfa was de-registered and taken off the road. The car's subsequent history is unclear until Giuseppe Bruni discovered it in Modena in 1960 and took it to a restoration workshop in Florence for re-commissioning. '8513033' remained in the Bruni family's possession for many years, and it is believed that additional restoration was undertaken by Autofficina Faralli near Pisa, Italy, between 1998 and 2000. It seems most likely that the largely new body in Zagato's original style was fitted at this time. Most if not all of the body panels have been replaced. 

Following a detailed examination, renowned marque expert Siegfried Otto Hepp has stated that '8513033' retains its original chassis, engine, gearbox, rear axle, front axle, and steering box. These parts were found to be numbered correctly and matching, with identical numbers stamped on mating faces, showing that they had always been together and that no other numbers are present.

In 2005, the Alfa went to the United States, becoming part of a private collection in Houston, Texas. It returned to Europe in 2008. In 2011 the car's chassis frame and the engine were analysed by two different institutes, one being the RWTH University of Aachen, Germany, and both clearly concluded that the steel and aluminium used in its construction date from the time it was built by Alfa Romeo (1929-1930). We can thus safely conclude that the rolling chassis is entirely original and just as left the factory in 1930.

An engine overhaul carried out in 2017/2018 in preparation for the Mille Miglia revealed 'SF' (Scuderia Ferrari) logos on the crankshaft and con-rods (pictures on file). It is claimed that this is the earliest documented example of Ferrari's 'signature' on a competition car. An old Ferrari hand has stated that all the components changed by the Scuderia's mechanics were marked with a little 'SF' logo initially, and from mid-1932 by a little 'Cavallino Rampante'. The crankcase has the same number as the crankshaft. New pistons were installed during the engine rebuild together with a new oil pump, water pump, flywheel, and clutch plate. Other works carried out recently include renewing the front suspension leaf springs, gearbox internals, axles, and fuel tank. 

In 2017, the original supercharger and carburettor underwent a full rebuild at the renowned specialists, Jim Stokes Workshops in the UK (see bill on file). An interesting detail is the Memini Type DOA twin-choke carburettor's cast-in auxiliary fuel chamber, concealed behind the normal float chamber; this modification is believed to have been made on competition cars to eliminate a 'flat spot' that occurred during circuit racing, possibly due to fuel surge on banked tracks like Brooklands and Monza. Interestingly, this car also has a double 'Auto-Vac' fuel system, only used for racing, which is believed to be another in-period installation.

Recently another car surfaced in Germany claiming the same identity, though research has proved that it is not the original chassis '8513033', as confirmed by marque specialists Siegfried Otto Hepp and John De Boer. The current owner of chassis '8510033' has spared no effort in establishing its authenticity. Multiple specialists have investigated this car, and a chassis scan has been carried out by recognised specialists Rennsport in the UK. This scan indicates that the chassis frame and engine stamps are original. Furthermore, renowned identification specialist, Siegfried Otto Hepp, has confirmed in writing that the numbers on major parts such as the front and rear axles, steering column, compressor, and gearbox are correct for a 4th Series 6C 1750 Zagato with a build year of 1930 (see report dated December 2012 on file).

'8513033' comes with a quite exceptional history file, which prospective purchasers are encouraged to inspect. Contained within it is a copy of an old photograph annotated 'con Enzo Ferrari in Bologna', which suggests that Enzo should be on that photograph, although it is hard to tell where he is! Also present is previous owner Giuseppe Bruni's logbook recording details of all journeys undertaken, kilometres travelled, problems encountered, oil changes, etc from the year 2000 onwards. He was clearly also a very good sketcher. Additional to those documents mentioned above, the file also includes:

I am not a natural flatterer, I like to think that I "tell it like it is", politely I hope. So when I tell you that I am very impressed by the contents of your website, it is just not English politeness. I of course love the subject matter but you deal with it in an energetic and respectful manner. I am overwhelmed by the research that has gone into compiling the list of coachbuilders/bodybuilders for Europe and North America. I have never heard of the vast majority of them. Congratulations on an excellent website.
