The Christie's controversy

Early 2007, Christie's created some turmoil when it auctioned the Karassik/Kogan Typ D. In the brochure, it was presented as chassis number 21, engine number 37 and the winning car of both the 1939 French and Belgrade GP.

Controversy arose when it turned out that Peter Kirchberg, Audi Tradition's chief expert on the Auto Unions, had said something quite different in his 2004 book Dem Silber auf der Spur. On page 14, he assigned French GP winner Müller to car 76010, with chassis 11 and engine 37. In Belgrade, Nuvolari had driven 76010 with chassis 22 and engine 29.

Some experts then added to the controversy. They showed that, in the early 1990s, C&G rebuilt the two-stage blown engine 37 in the Karassik/Kogan/Christie’s car by converting a single-stage blown engine, which has different parts. Meaning: current engine 37 cannot be the same engine 37 as was used in the 1939 French GP. It also has a new cilinder head, built from scratch, since the old one had corroded badly.

It should also be noted that Belgrade winner Nuvolari actually drove car 76011, which had chassis number 26 and engine number 26, according to the Auto Union archives. A copy of this archived document can also be found in Kirchberg’s older book Grand Prix Report Auto Union 1934-1939. Car 76010 had originally been assigned to Nuvolari, but since he did not show up at the practice days and his arrival was not assured, 76010 was given to Müller.

On March 1, 2007, Christie´s announced that it had completed its research with the aid of Audi Tradition. They claimed that the car´s chassis is frame 19, not 21. Regarding racing history, the press statement said "that chassis 19 is a genuine 1939 Typ D chassis and that it was first raced by Rudolf Hasse in the Eifelrennen on the 20th May 1939 at the Nurburgring, in which Hasse finished in 5th place. It was next raced at the 1939 French Grand Prix in the hands of legendary Auto Union pilot Hans Stuck, who brought the car home in 6th place, behind the company's 1st and 2nd finishers."
