Dave, can you please take a look to this thread?
http://www.early911sregistry.org/for...688#post209688.
(Uncovered! short-lived third model: the 1967 911 deluxe").
I've sent there some pictures of my 66-67 911 with a very strange engine; you already have it in your list. The weird question is it has Solex carburettors and it looks like original. 901/5, 909445, build number 5703.
(pages 4 to 5).
Thank you.
Jose.
