I have found this car referred to as "Jaguar Elgaram" in a Classic car photography site. Also, the following text:
"The Bolwell Mk3 started life as a Jag/Healey special originally built by Graeme’s dentist. It featured a new Austin-Healey chassis with Austin-Healey front suspension, rear axle, wire wheels, and had Dunlop SP racing tyres on it. It came with a hotted up Jaguar Mark VII engine and gearbox that had D type valves, cams and other go faster gear, and it performed very nicely. It would do a standing quarter mile in 13.9 seconds at 102 mph.
The original fibreglass body was a bit heavy and was generally considered to be “ugly”. Graeme didn’t like it so eventually he put a body of his own design on it. This was to be the first fibreglass body built by Bolwell. There was a centre bulkhead made out of tubular steel and covering that in aluminium. The doors were made out of steel but fibreglass was used for the bonnet and back panels. Graeme utilised the rear window from an FE Holden as his windscreen. Graeme’s Bolwell Mk3 was eventually put up for sale in December 1963 and subsequently became known as “The Elgaram”.
Graeme’s Bolwell Mk3 was advertised for sale in “Australian Motor Sports” magazine December 1963 as a Jaguar-Healey Sports. The car was eventually traded in at Pitstop Motors in Frankston and purchased by Rex Styles in February 1964 for the sum of £17. Rex used it as a road car and raced it in hillclimbs and other events as “The Elgaram” (this was based on Maragle Street spelt backwards). The Elgaram has since passed through several owners and has had considerable changes since its first inception, including being fitted with a Ford Customline engine, a Holden FC engine, and a Jaguar XK120 rear end.
The last that was heard of the Elgaram was that a new owner was restoring it back to its original Bolwell specifications with a 3.8 litre Jaguar engine, and so on."
