I have just a couple of pics of it...they came from Amsterdam - Amersfoort area but there's nothing much about it.
It had a VW chassis, no engine and Italian license plate.
Here's an automatic translation of what I have:
"My first kit car not built by myself but bought in 1967 for FL. 25. There was no engine and I had to push it home with my friends. It had a VW-chassis and there was no valid vehicle registration. I've had an Italian license plate set up that I had gotten by former racing driver Jan Brandsma who along with Rob Dijkstra formed the Sony racing team. In really have (without a license, that could then) in driven we reason about the old state road Amsterdam-Amersfoort and Baarn back to the bit of Bussum, be 110 km per hour."
