Donald Healey’s 1953 debut of the lithe and advanced 100-4 was followed by success on racetracks around the world, which were seeing Austin-Healeys in ever-increasing numbers. Through 1954, five 100-4 models were outfitted for racing and campaigned as works entries at major events such as the 24 Hours of Le Mans and 12 Hours of Sebring. This development work culminated in the 1955 Austin-Healey 100S, which was distinguished from standard production 100-4s by its aluminum body panels, four-wheel Dunlop disc brakes, and an advanced aluminum cylinder head developed by Harry Weslake which, along with other modifications, added 40 hp to the output of the 2,660 cc inline four. Hand built in a separate workshop, just 50 production 100S models were constructed, and they have remained among the most competitive and desirable British roadsters of the era.

This 100S, chassis AHS 3901, was sold new through French Austin-Healey agents AFIVA to pioneering French-Brazilian racing driver Hermano “Nano” da Silva Ramos. Da Silva Ramos was the first French-Brazilian driver to compete at both the 24 Hours of Le Mans and in Formula 1. Competition results for AHS 3901 from Nano’s time with the car are not known, and it was later sold to Bernard Maitre of Paris, and subsequently to Glyn Lambert who chronicled, in an article on file, his adventure purchasing the Austin-Healey in Paris and driving it to London. The 100S was then imported to Australia and, in 1980, it was acquired by collector John Blanden, having been freshly restored by former owner and 100S specialist Steve Pike. Blanden raced his 100S in historic meetings around Australia and, in 1998, loaned the car to Stirling Moss, who drove it at speed in an exhibition for the 1998 Australian Grand Prix. Moss was smitten with the Healey, suggesting AHS 3901 to the consignor when Moss learned he was searching for one. Purchased by the consignor at a 2001 auction in Australia, the Austin-Healey was imported to the US and has spent the subsequent 23 years being dutifully maintained as part of the consignor’s respected collection of sports and racing cars.

Chassis AHS 3901 remains in its proper specification, even retaining its original engine and gearbox, according to the consignor. A high level of stewardship and care is demonstrated by its appearance, and the quality of its decades-old restoration is still quite evident. Accompanying the 100S at auction is a background file that contains copies of numerous accounts of the car’s history, invoices, and photos that include Stirling Moss’ drive in Melbourne, Australia.

These very important competition specials are among the most desirable British roadsters of their era, and the opportunity to buy one can be fleeting. Offered from caring ownership and poised to provide entry into many of the world’s great driving events, this Austin-Healey 100S should be on a very short list for enthusiasts of mid-century motoring.
