‘Blue Buzz II’ headlines docket for Bonhams Monaco sale

1936 Delahaye 135 S Competition Court competed on the track and at concours


Nicknamed “Blue Buzz II,” a 1936 Delahaye 135 S Competition Court racing car that ran at Le Mans headlines the docket for Bonhams Les Grandes Marques à Monaco’ (aka The Monaco Sale) scheduled for April 23 as part of the Monaco Historic Grand Prix weekend. 

The car was owned by Irish-American heiress Lucy Schell for her Ecurie Bleu racing team and made its debut as part of the car’s three-vehicle entry in the Three Hours of Marseille. The car gained its nickname because of its sky-blue color and the muffled buzzing sound of its engine, according to Bonhams.

The car ran in Grand Prix races at Donington, Pau and Commiges and in endurance events including the Belfast Tourist-Trophy before going to Le Mans in 1939, when it was rebodied with more aerodynamic coachwork by Chappes Frères. 

Two subsequent facelifts followed, and the car was successful off the race track in various concours d’elegance. It will be offered at the auction with coachwork in the Chappes Frères style while retaining its original-period engine and chassis, which Bonhams says is a rarity for a racing car from the period.

The auction company expects the car to sell for €800,000 to €1.1 million ($950,000 to $1.3 million).

Also on the docket are:

  • A 1949 Simca Deho Barquette with coachwork by Motto. The car was the creation of racer Jean Estager who converted a Simca Eight into a racer with a 1,086cc engine by Roger Deho and a hand-formed  aluminum body by Motto of Milan. Estager sold the car in 1951 and it was entered at Le Mans but did not make the starting line. It later raced at various venues.

The car was rediscovered, stored away in a barn, early this century with its original chassis and engine. A restoration was done, except to the interior of the driver’s door, which was retained “as a reminder of how it was found.”

Pre-auction estimated value: €190,000 to €240,000 ($225,000 to $285,000).

1947 Cisitalia D46
1947 Cisitalia D46 monoposto
  • 1947 Cisitalia D46 Monoposto, one of 14 produced and one of 12 known to survive. Bonhams reports that this car is believed to be the one driven in the Grand Prix de Bern by Harry Schell, the first American to start a Grand Prix race.

The car later was driven by a succession of Australians before it was purchased by Belgian racer Paul Swaelens, who had it for more than 40 years, selling it to the consignor in 2003. The car since has been fully restored, Bonhams noted.

Pre-auction estimate: €150,000 to €200,000 ($177,770 to $237,025).

*1991 Isdera Imperator 108i, a supercar resulting from a Mercedes-Benz design experiment in the late 1970s by Eberhard Schulz, an engineer who formed Isdera to put the design into production and made 30 cars over a period of nine years.

The car has gullwing coachwork over a tubular-steel chassis and is powered by a 5.0-liter M119 V8 engine. 

Pre-auction estimate: €500,000 to €700,000 ($592,560 to $829,580).

The Bonhams Monaco Sale is scheduled for April 23 at the Fairmont Monte-Carlo overlooking the hairpin turn on the Monaco Grand Prix circuit.
