Charlie, this is going to be a strange answer...no and yes. Let me explain.
In the May, 1933 issue of Golf Illustrated an article written by Tilly with the title, "The Genius of Pine Valley," in speaking about George Crump, he stated: "True, he sought opinions from others. I was one of the first to walk the property with him and that George Crump finally incorporated two of my conceptions entirely (the long seventh and the thirteenth) will ever be the source of great satisfaction..." [bold mine]
Corroborating this, sixteen years earlier, in the August, 1917 issue of Golf Illustrated, in his column, "Our Green Committee Page," Tilly wrote the following: "Not long since someone at Pine Valley Golf Club asked George Crump when the course would be finished?
"'Never' he replied. By this he meant that after the four undeveloped holes were thrown open, work, aside from upkeep, would continue indefinitely. New features will be introduced after careful consideration and many minor changes are certain to be made. To illustrate this I have roughly sketched from memory the long hole from at Pine Valley, the seventh.
"As it was originally planned is shown by Fig. 1. It is being played so at present and a mighty fine hole it is, too. None but the long hitter even hope to get within striking distance of the green after his second shot, and both the drive and the second shot must be hit. An enormous area of sand extends quite across the course, beginning, I should say, 325 yards from the teeing ground. The hazard must be close to 100 yards across. If it is not carried, the green is beyond range. But good as it is, some variations from the present lines will make it a far greater problem, and the change will be made.
"Along the right of the fairway extends a wood, and cuts will be made for this new teeing-ground and for the second shot. After the change the tee-shot must be played more to the left than at present, the second shot will be forced to the right, and naturally the green will open up to an approach from that side. A comparison of the two sketches [included in the article] reveals a marked improvement with not an alarming amount of work in sight. Already the new green has been constructed."
So why the answer "no and yes?" Because the original hole as designed had the Hell's half-acre bunker in it. Did Tilly have input on the original design of that hole? No one can say for certain one way or the other. He did redesign the hole, Hell's half-acre included, making it an early example of his concept of a "double- dog-leg" par-five, and as he noted in the 1917 article, the hole was being rebuilt at that time per his recommendations. This was confirmed in his 1933 article.
