No way a long shot!!!! Vertex made me one, oac model, with the 1966 s-model advance curve.
I still got it, its never driven any meters...
I have the documents also for that. And i could even sell it. :-) ...
I think it has to be pretty rare, because they told me that it was the first they ever made to a porsche six cylinder.
:-) let me know if you need it ....
There might be a picture in my blog.
