I'm sorry that I didn't respond to the comment re wanting to know more.
Ron Learnan was an engineer by training, educated in NZ in the 1950s, and wound up in the UK for a few years during which time he bought a brand new Cooper 500. He crashed it a bit later, repaired, and modified it to the point where Coopers apparently disowned it, and it became the RGR, now back in the UK after many years in NZ.
Ron decided he needed a road car, so set about building Volcoupe(e). It shares many dimensions with a Cooper 500, much of the same suspension layout, "wobbly leaf" transverse springs and such. It had a midmounted VW engine in a space frame and was a very effective little car. Ron used it daily to drive the 25 odd miles each way to work. Wheels were cast by Ron and friends with cast iron liners in the alloy centres which have Renault 4CV rims bolted to the outside as per Renault. Wishbones are all fabricated, front uprights fabricated, rears suspension is a combination of VW axles, transverse spring, and bespoke parts to make it all work very well.
The alloy body with gull wing doors, uses a Hillman Minx rear screen as the windscreen. I first paid money to buy it in 1967, paid a deposit at one of the many dodgy car dealers in Auckland, then went back a week later to finalise the deal, and was told they had sold it. Refund of deposit? Of course not, which hit an impoverished student very hard.
I found it again many years later (1990?) and this time paid and collected the collection off bits very quickly. Family/housing needs got in the way, so I sold it again, loads of restoration work done, but incompleted.
