HELP 911S 1967 canary yellow VIN 307583 S last driven in NY Long Island Greenlawn

Hi!

I am searching for some info about the history of this car. It was last driven in NY, Long Island, Greenlawn. Last owner was John C. Howell in Greenlawn NY.

As I can see from the original Production Card, this car was first delivered on 13.03.1967 to Dr. Kurt Tomek in Kaiserslautern (Germany) and later it was sold to Heinz Keller in Karlsberg.
My last piece of information is, that Adam from Unobtainium bought the car from John H. in Greenlawn, NY on Long Island. John registered it there in 1995.

So there is a gap between 1967 and 1995 during which the car was exported to the US.

Can anyone help me and does anyone have any information about his car or a privious owner?
Or does anyone has contact to this area?

I would appreciate any help! Thank you very much in advance!
Christian
