Friday's Ferrari

I took this photograph at the Coys International Historic Festival meeting at Silverstone in August 1996.

It's a Ferrari 250GT SWB, but I've not been able to identify the serial number of this car, which appears to have the registration number 250 SPG. There were three 250GTs entered in the 'Coys of Kensington GT Race', two of which were red according to the programme of the event, The records of www.barchetta.cc doesn't record this car as belonging to either Jose Albuquerque or Ian Donaldson who entered those two cars on that day. In fact I can't trace any 250GT that's ever had this registration number.
