Jaguar D-Type Replica

I took this photograph at the Jaguar Drivers' Club's Cheshire Cats Trophy Meeting at Oulton Park in April 1987.

It resembles a 1956 Jaguar D-Type, but it's obviously a replica as the shape of the car isn't quite right. I can't find out much about the car, except that the DVLA says it's a Jaguar that was manufactured in 1970 and has a 4,235cc engine - which is the capacity of the 4.2 litre version of the Jaguar XK engine.
