Dulon LD11 P

This was a Porsche engined sports racing car that raced in 1971/2 around the UK and Europe. I'm wondering if there's anyone in the club who has knowledge of it and in particular, one of its drivers, Martin Ridehalgh, who would be about 72/73 years old now.

Interested to see a mention of this one-off, Porsche-powered Group 6 racing car. Dulons were produced for ten years and while some were sports-racing cars the majority were single-seaters, mainly Formula Fords although they also made a one-off Formula 5000, a GT racer and the prototype of a very nice-looking GT road car.
The company was founded in 1967 and early in 1971 the second of the two LD11’s was built (#41/2/71) with a 2.0 F6 engine of the type used in the 906 and 910, the other (which was written-off in 1973) having Ford FVA power. The design was a development of the 1.3L LD10 -although one had a Ferrari engine; another story!- and apparently the well-known Porsche specialist of the day Chris Maltin had some input into the development of this Porsche version.
The car was raced internationally on a shoestring budget for two years by Martin Ridehalgh and one or two other drivers with rather mixed results and is unfortunately best remembered for having accidents with the works Ferraris of Ickx and Regazzoni at separate events during 1971. Fortunately Ridehalgh kept the car after retiring it and in the early 1980’s it was sold, rebuilt and eventually returned to the tracks in historic racing with a 2.7RS engine, although the reinstating of a correct unit was planned.
The car was apparently featured in Porsche Post back in 1993 and I have the picture below (from an unknown source) on file. It shows the car at the 1971 Spa 1000km where Ridehalgh share the driving with Ian Taylor and they qualified 23rd out of 28 before the accident with Regazzoni put both cars out of the race. The LD11P was a brave attempt at something different by a small company and raced alongside the big name cars and drivers of the day, such as the works 917’s.
