This car participated in the race for the Historic Seaman Trophy at the Richard Seaman Historic Trophies meeting at Donington Park in June 2003.
It's a 1938 Alta Voiturette and was driven in the race by Martin Redmond. The programme of the event said this about the Alta entries:
The two Altas, that of David Baldock driven by Paul Jaye (121) and the other of Martin Redmond (4), can always be expected to challenge the rest. The Alta with its very advanced chassis with all independent suspension was designed and built by Geoffrey Taylor in a small workshop in Tolworth, southwest of London.
It looks as if this particular car was the subject of an H&H auction in July this year, but didn't sell.
