Hi Dave7,
This is most likely a JPR Wildcat. These were built in the UK by John Randell at a factory based at the Goodwood Circuit. They were typically based on Cortina running gear but John offered to re-jig the chassis for other donor cars if possible. Take a look at

The club are aware of cars that were exported to many parts of the world and my have some info about this one.
