I didnt know these details. The car i built was a "kit car". It was called the Hussler. I didnt know it was based on this earlier design. 1300cc engine , and a greenhouse in the summer. One was found in a UK scrapyard recently.
I built one of these , around the late 80,s. Im from the West Midlands too. I wonder if many recognize it , or know its name and origins. One was discovered recently in a scrap yard.
