This is a car photographed at the Christie's International Historic Festival meeting at Silverstone in July 1992 which featured a special Ferrari display.
It's a 1979 Ferrari 512 BB/LM and the programme of the event had this to say about the car:
Mid-engined flat 12; 4.9 litre; 480bhp at 7200rpm; twin
ohc per bank; fuel injected; all-round independent
suspension by A-arms/coil springs. A number of these
were built in mainly 1979 and to meet the 'Silhouette'
regs which required cars to have some resemblance to
the production versions in the windshield, doors and roof
The car is serial number 27577, originally an Ecurie Francorchamps car and owned by Nick Mason in 1992.
