I think this is Norm Bolitho's race car transporter, "Dennis the Menace", built on a 1971 Dennis fire engine chassis. The unit is purpose-built to take the team's classic Volvo 142 or vintage Chrysler competition vehicles to motorsport events across Australia. I looked up Nigel Webb's transporter for his D Jaguar, and either there are two nearly identical vehicles (doubtful), or they are one and the same. Don't really know what to think on this one, but the reality is, it's one (or two?) VERY neat transporter(s)!!!
