The astonishing group of competition cars belonging to Australian historic racer Peter Harburg is to be auctioned in Paris next year.
The collection, which includes some especially tantalising Porsches, will go under the hammer at RM Auctions' 4–5 February sale during Rétromobile week.
Star Porsche will be a 917/30, one of only six 1973 5.4-litre chassis prepped for Mark Donohue in CanAm. Wearing the famous Sunoco livery, this chassis never saw action in period, but is still expected to bid to more than €2million.
The same estimate is being put on the 1982 956 Group C Sports-Prototype (chassis 004) that finished third overall at Le Mans – part of a Porsche clean sweep – piloted by Hurley Haywood, Al Holbert and Jürgen Barth.
Other Porsches from the collection include an ex-Dickie Stoop 1964 904 Carrera GTS (€1.1million),
Non-Stuttgart machinery will in some cases be even pricier, including a Jaguar D-type (XKD 520) with Bathurst history (€4.1million) and a 1955 Ferrari 750 Monza Spider (below) with Sebring, De Portago, Schell and Taruffi history. The Ferrari is estimated to make €1.8million.
Other key lots are a 1959 Porsche 356 A Carrera 1500 GT Speedster (€740,000-1.1million); the 1950 ex-Briggs Cunningham/Sebring Aston Martin DB2 (below, €277-350,000); a 1987 Porsche 959 (€330-€380,000); an ex-John Coombs 1971 Ferrari 365 GTB/4 Daytona (€295-333,000); and a 1969 Lola T70 (€295-355,000).
