OK, so to put this puzzle to bed it's probably easier to quote verbatim what information I have so please excuse the 'plagiarism'!
"Built in 1951 in the workshop of Messrs Moore & Tye of Hastings.... Bodied in aluminium, with a wooden floor, and mounted on a tubular chassis, the car utilised a number of Ford V8 Pilot parts including the engine and transmission"
"The car was built for an Eastbourne chiropodist,a fact borne out by the 1951 Eastbourne registration AJK 151. Many features bear an uncanny resemblance to the JAG cars built at Thames Ditton by John A. Griffiths from 1950, also Ford V8 powered, and one wonders if the 1950 JAG provided the inspiration"
Anyone know whereabout Moore & Tye were based? I'm off to Hastings on Saturday, it'd be interesting to have a look at the site of the workshops.
