Try this one then...


What on earth is it (its amazing what you can find in 1960s books)...
The cars may give a clue to its country of origin.
Its designer also had links with another aeroplane from the Real Air Simulations hanger...

I remember seeing photos of this years ago. Forget what it is now. Gotta be a SAAB. Possibly a jet version of the Safir. That's all I can think of.
Mmmm, I think they might be FIATs or Alfa Romeos in the background...
PS. If it's Italian it looks very much like the SF260.
