Aha - I thought this would be easy to find! No way, I've just spent all afternoon trying to find it!
Anyway, I made the mistake of thinking this car was from Europe - wrong! so I wasted a lot of time with that (not totally wasted as I found some interesting things whilst searching - I found that Luigi Taveri, the multi-world championship winning motorcyclist recently gave a demonstration at the Oldtimer Expo in Budapest, Hungary. Amazing - he's 83-years old next month!
To get back to the puzzle car - it, as I thought earlier has been built on an early Formula Vee mechanical base and has been created to resemble the early Gloeckler-Porsche sports car.
The man responsible is Chris Runge, based in Minnesota, USA who had been wanting to build an aluminium bodied sports racer for several years. He has done a splendid job - building a buck and shaping the aluminium bodywork.
Chris Runge has his own website that gives full details of the construction process.
Oh yes, the car does have a name - it's called the "Frankfurt Flyer".
Two photos for comparison - the first is the original Gloeckler-Porsche and the second, the just completed "Frankfurt Flyer".
