1930 ALFA ROMEO TIPO 6C 1750 GRAND TURISMO SPIDER
Chassis No. 8613381
Engine No. 8613381
Red with tan leather interior
Engine: six-cylinder, twin overhead camshafts, supercharged, 1,752cc; Gearbox: four speed manual; Suspension; semi-elliptic leaf springs front and rear; Brakes: four wheel mechanical drum. Right hand drive.
The 6C series was founded in 1924 when Alfa Romeo engineer, Vittorio Jano, was instructed 'to develop a medium capacity light car with brilliant performance.' The great engineer chose the balance and pick-up characteristics of an in-line six cylinder engine and combined them with a very lightweight and nimble handling chassis design. Much experience was gained in the development of his AIACR World Championship winning Alfa Romeo P2 Grand Prix car of 1924-30, which was built into this production series.
The prototype, initially known as the 'NR' but subsequently renamed '6C 1500' was unveiled at the Salone dell'Automobile Milano in April 1925, and then reappeared at both the major Paris Salon and the London Motor Show. Deliveries to customers of the original single-camshaft version commenced in 1927, and the general reception was so enthusiastic that a second series of twin-cam variants followed. Many 6C 1500s were employed in competition, with supercharged variants doing particularly well in sports category events in 1928 and 1929.
The subsequent enlargement of a similar basic engine configuration to the 6C 1750 model form involved increases in both bore and stroke from the 1500's 62mm x 82mm to the 1750's 65mm x 88mm, displacing 1,752cc. These engines were offered with or without supercharging. Significantly, the supercharged 1750 engine developed considerably more mid-range torque than the unblown unit, which made it a most effective weapon for racing and hill-climbing, while also doubling as a genuinely high-performance sporting road car. The 1750 Alfa Romeos, particularly those with lightweight open spider coachwork, have a tremendous reputation as well balanced and enjoyable cars to drive with surprisingly high qualities of acceleration, braking, cornering and handling that few contemporary cars can match.
This Alfa Romeo dates from 1930 and is designated as a fourth series chassis. While the car carries no coachbuilder's plate, it is almost undoubtedly the work of Carrozzeria C. Castagna & C. of Milan. It displays classic Castagna coachlines and features such as the spears on the bonnet and intricate keys for the glove compartments. Bill Lassiter acquired this car from a European auction held in Monaco on May 22, 1990. When catalogued for that auction, the car was similarly described as a Castagna bodied example and we concur, although we have no documentary evidence to support the car's early history. This vehicle reputedly spent a long period of time in South America before returning to Europe.
When Bill received his new Alfa Romeo, he was upset to discover that mechanically the car was in poor shape. In the early 1990s, Jack Dietz carried out a major engine overhaul including fitting new roller bearings, grinding the crank, re-profiling the cam shafts, installing new gears and drive bearings (supplied from a UK specialist) and rebuilding the oil pump and gears. At the same time, the clutch throw out bearings were replaced, the carburetor/generator and starter were overhauled and the radiator was re-cored. Cosmetically, new leather was fitted throughout, including on the rumble seat, new carpets were fitted and all the woodwork was re-varnished. Jack also made a new windshield frame, glass and posts to enable the windscreen to fold flat. The car comes equipped with twin mounted rear tires. Since the engine rebuild, this beautiful 1750 Alfa Romeo has had very limited use and may require careful running in.
