With the help of google, companies register etc, I located and sent the original owner of my car an email with pictures of my car as it is today.
As it turns out his son, who is also a Porsche enthusiast, got the email and read it to his dad and showed him the pics. The elderly gentleman was delighted to find out his SC was still in going order and living on the other side of the world. Sadly the gentleman was in his last two months of life, but his son said it really made his day to see pic's of his old car.
The son went through old photos of the various Porsches they owned and sent me a couple of pics they took when they bought it new in England.
