These are a series of historical GT-40 pictures - primarily focusing on John Horsman, who was the chief engineer for John Wyer Racing during the days of their Le Mans victories in the late 60s and early 70s with the GT-40s and the Porsche 917s.
Here's a link to a slideshow of multiple historical pictures on Photobucket. Enjoy. Chuck H. http://s1298.photobucket.com/user/Rocky_LC/slideshow/Horsman%20Photos
