My feeling on this is that the newspaper artist had Mackenzie's bunkering plan at hand to copy and make a version that could reproduce easily in newsprint, so a lot of Mackenzie's fine linework that we see on his Royal Adelaide plan would have been left off the copy. I believe it would be a reasonably accurate depiction of Mackenzie's plan but, alas, we will never know for sure. In any event, I don't think Morcom and Son were all that worried about following the plan to the letter, in fact they informed the club at the start that they would need to vary from the plan in some areas, so it would not surprise me if they took a bit of license to change more than a little. 3 would be interesting with the bunker moved out a bit into the fairway - go for it Clayts!
