1964 Lotus 30

This car competed in the World Sport Car Masters race at the Silverstone Classic meeting in July 2010.

It's the 1964 Lotus 30 of Matthew Watts, and according to the programme of the event has a 5300cc engine. The Lotus 30 had a backbone chassis similar to that of the Lotus Elan instead of the space frame chassis of Colin Chapman's last sports racing car, the Lotus 19, and was intended to compete in Can AM racing. Lotus engineer and designer Len Terry refused to have anything to do with the car because he considered that the backbone chassis would not give sufficient torsional stiffness, and except for some early encouraging results at the hands of Jim Clark the car wasn't a success. The Lotus 30 was originally built with a Ford 289 cu in (4,727cc) engine.

Three Brabhams

I took this photograph at Foulstons chicane on the first lap of the HSCC Classic Racing Cars race at the Gold Cup meeting at Oulton Park in August 2004.

Leading is Steve Worrad in his 1970 Brabham BT30 followed by the 1965 Brabham BT16 of Matthew Watts and the 1970 BT28 of Edwin Jowsey. The Brabham BT30 was designed to compete in Formula 2 races when the engine was limited to 1,600cc, and Steve Worrad's car is chassis #BT30/25, originally raced by Rolf Stommelen. The BT16 was built for the earlier Formula 2 series when the capacity limit was 1,000cc, though the programme of this event shows Matthew Watts' car to have a capacity of 1,594cc. The Brabham BT28 was designed for Formula 3 racing when it had a 1,000cc limit, but the programme shows the engine of Edwin Jowsey's car to be 1,600cc. This car is possibly chassis #BT28/04. This website lists all the different types of Brabham racing cars. The programme has this to say about the race:

'Another over-flowing grid of 1960s single-seaters will line up for round seven of the HSCC Classic Racing Cars Championship. Cars from Formula 3, Formula 2, Formula Junior and even Formula Ford are all in the field, which should be headed by the 1600cc F2 Brabhams of Edwin Jowsey and Steven Worrad. 

Young Jowsey has had his share of bad luck this season in the BT28, but if that is behind him he will be very tough to beat. Worrad, meanwhile, has a BT30 and will surely take the fight to Jowsey along with championship points leader Matthew Watts (BT16), Jim Gathercole (BT30) and John Moulds (BT23).'
