The Wizard Roadster is a bit of a knock of of the coachbuilt Maier.
Pretty sure the kits are still made in England.

The Maier Conversion - 1952
The Swiss coachbuilder Werner Maier was commissioned to make three convertibles in 1952 after the closure of the Hebmüller factory. The Maier design was strikingly similar to the Hebmüller.
The coachbuilding work was farmed out to Karl Rusterholz whose karosserie was near Zurich. Each of the three conversions took 6 weeks after delivery of the original Beetles. Had their price not been so high and had more support from Volkswagen (the price of the original Beetle was added to the cost of the conversion) they may well have continued where Hebmüller left off.
Unlike the Hebmüller, the Maier retained semaphores and featured a short decklid within the sweeping rear bodywork. Only one Maier survives to this day.
