Steve:
I've followed Drew's work at Plum and have met with him and Plum member Jay Hults several times to discuss Alison and Plum. The comments re Alison are straight on. C&A called it "their" course until Wilfrid Reid came in and redid (added/subtracted?) the bunkering in the mid to late '20s. Then it disappeared from their list. So we talked scale and "ferociousness" of Alison's bunkers vs Colt.
We (historians and the club specifically) have almost nothing re Plum and Alison. No drawings, routing plans, pictures from the '20s, etc. They had a clubhouse fire, sound familiar? Drew has done excellent work "in the manner of" and we should all be happy with Plum taking on Drew and doing it right (or Alison). His work on 11 thru 13 alone would be worth the price of admission with tree removals and more exciting use of the ravine edges, river bed, etc.
Hopefully somebody with photo skills, both in the field and on the computer, can post here. The before and after photos will be informative and stunning.
