I photographed this car at the Coys International Historic Festival meeting at Silverstone in July 1993 waiting in the paddock to go onto the track to take part in a practice session.
It's Hubert Fabri's 3-litre straight-6 1955 Aston Martin DB3S. Starting in 1953, ten cars were built for the works Aston Martin team and growing demand for a production version caused Aston Martin to build a series of 'customer' cars starting in 1955. OXE 472 was one of three customer cars delivered to Australian Tony Gaze's Kangaroo Stable in that year and is chassis DB3S/102 (the other two were DB3S/103 & DB3S/104 and were registered as OXE 473 & OXE 474). DB3S/104 was sold by Sotheby's in 2009 and here is their description of Lot 562 at that auction.
