Tab books Inc. put out a book several years ago entitled The Cessna 150 and 152. On page 15 of that book is a picture of a early model aka '59 model C-150.  Althought picture is B&W it still shows the lines that you are looking for.  As for me, I am looking for the original paint scheme for my D model, a 1964.

Hope this information is helpful for you in your search.  I also remember that Plane and Pilot published a story about a 1959 C-150 with the original paint scheme.  You might check their inventory listing or call the publisher.
