I thought, for sure, that Tom Paul would attack this post with gusto! In any case, I have often heard the 17th green attributed to Perry Maxwell; however, little evidence seems to support that.
In David Goddard's definitive work, "The Maidstone Links," he suggests that the the second hole's green was the product of, perhaps, Seth Raynor, who assisted C. Wheaton Vaughan in his 1916 work: "Macdonald and Raynor built Road greens everywhere... It is too much of a coincidence not to think that Raynor added this green at Maidstone in 1916, and that Park thought:well, why not. There is no record, lastly, that Park ever built a similar green anywhere else." Goddard goes on to say:
"The seventeenth, though, perhaps raises a question in respect to its authorship.. Like the first and second holes it was on the old course (the original fifth on the Florence Quick lot). It has some of the earmarks of a Willie Park design -- two tiers and a slight fall-off at the back which he sometimes used. But it is small, quite quirky in comparison to all others on the course, and bears some resemblance to a Road green as well. For the second shot the hole is set up to play like the seventeenth at St. Andrews. All the reward is on the right side of the fairway and the risk on the left. In those days the road was sand and there was no fence. Many a third shot would have been pitched from the right of the green, from the road itself."
The only record of Perry Maxwell showing up at Maidstone is in 1939, after the hurricane caused extensive damage to the course. Maxwell had drawn up some plans to suggest improvements, but, ultimately, his plans for a simple (and inexpensive) restoration were adopted. If he did work on the 17th in that year, someone should remember it!
I've exhausted my typing abilities for the moment; I'll try to respond to your question more directly later. This weekend, I'll be out there and will try to snap a few pictures for you (but no promises).
