Here's a little more oral history from an old Dick Wilson thread from Adam Messix:
"This is an interesting discussion on Wilson. At Plymouth Country Club, Flynn was the Architect who designed the course while Wilson and Ellis Maples were "Construction Supervisors."
What is interesting is that Wilson designed a course on his own that same year, Pine Crest Country Club in Lumberton, NC. Wilson was brought there by Daisy Sunday Meehan and her brother Pete Sundy whom Wilson had become aquainted to during the Sundy's time living in Delray Beach, FL. Wilson designed the original nine holes of Pine Crest (FKA Lumberton Golf Course). The course was constructed using WPA funds. The design, the green complexes in particular, remind me of Plymouth. They have very much a "Shinnecock lite" look and have collars that are mowed at fairway height where a ball with run off down the hill. Wilson's hole are today #1,2,3,8,9,10,11,17 & 18. There have been a couple of changes, the current 8th green was moved further back and the hole changed to a par five, the 10th hole ws lengthened, and the final green were redone in 1955 and it blends in with the surrounding terrain much more than the rest of the Wilson holes. The bunkers were rebuilt by Russell Breeden during I believe the 1990s and don't fit the Flynn style that was built at Plymouth. Although the exact dates of when he was at Plymouth cannot be confirmed, we know that Wilson left Plymouth and went to Pine Crest.
Donald Ross designed the other nine holes in 1946 and were constructed in circa 1955."
