Sunningdale New has gone through several changes through the years, original Colt course, Simpson made some changes, then Morrison/(Colt) abandoned most of Simpson's changes and made several themselves! All the changes were mostly through the 6-9 stretch. I'll try to post the details later.
Anyway, here's Colt's original 7th-now defunct. For those who know the course: after the 5th, instead of turning left to the current (great) 6th, the course continued straight ahead, into the open heath.
This looks like it was a truly great and adventurous hole! Very Pine Valley-esque?
I will post the original article that contained this pic. Just need to compress the file.
