TE,
I had always associated the moving of # 18 green to circa 1948.
Earlier, I had also questioned the accuracy of the dating of the aerial photos.
However, it seems unlikely that Wilson made the change in 1948.
It makes more sense, politically and otherwise that he made the change in 1963 when his individual popularity, architecturally was near it's high water mark.
In addition, Wilson was the greenskeeper at Delray Beach CC until WWII.
During WWII he was employed camouflaging airfields.
After WWII he partnered with Troup Brothers, an earthmoving firm.
He didn't begin solo design projects until 1947 when he designed Kinderton in Virginia, then Westmoreland in 1948.
Strangely enough, his redesign work at other courses didn't begin until 1955, with the sole exception listed by C&W of Seminole in 1947.
But, if aerials of Seminole circa 1948 show the old green intact, then C&W are in error on the date.
It seems to me that Dick Wilson, whose work I really like, wasn't enough of a force in 1947, to revise Seminole, in any capacity
