Study visuals of Tazio Nuvolari's 1935 German Grand Prix-winning Alfa Romeo - which slayed the might of that country's Silver Arrows - and a detail is unmissable: A yellow shield bearing the letters S and F and a black rampant stallion (Cavalino Rampante) graces the flanks of this red single-seater, specifically its (front) engine cover.
A tatty Nurburgring race programme provides clues to those initials: Alfa Romeo's race team was then outsourced to Scuderia Ferrari after an agreement was struck between the Milanese company and its former race driver, Enzo. No sooner had the 1933-38 deal ended than World War II intervened, and, only after hostilities ceased did the Modenese construct and race cars under his own name.
Ferrari's Alfa Romeo arrangement was little different from that currently in force between Joest Racing and Audi Motorsport, with the former effectively managing the latter's on-track operations in the World Endurance Championship. M-Sport, too, worked in similar fashion with Ford in the World Rally Championship, and does so today in conjunction with Bentley in GT series.
