The first is a actually the number 1 from 1969.
This car with body number 917-001 was a demonstration car completed just two days before the Geneva Motor Show and was never actually raced. Available for demonstrations and as a test vehicle. Still, it really looks the part with the original design being a little different from those later ones.
On the 50th anniversary of the car, Porsche spent a great deal of time and money on its restoration. Now in its original condition, the colour scheme is accurate to the first time it was displayed. You can read about the restoration in the article
