I found a copy of the original article. In the photo caption it says the builder was Dennis Haggerstone, but in the article itself the name is given as 29 year old author Denys Haggerstone of Hill Lane, Blackley, Manchester. I haven't been able to find an author under either name or anything on the car or the man other than this one article. As well as the information already given , the article says the car uses a Jaguar engine and has aluminium bodywork with "fish fin stabilisers". The headlights were fitted with a variable switch so they could range from a "dull glow to a searchlight beam". The bonnet could be removed for maintenance.
