Well, how about that!
You know, I had thought it a bit odd given Hugh Wilson's prior, well-received involvement in doing extensive rework, bunkering, and even new holes on the South Course (along with Strouse) that all of these years it was apparently easy to believe that there was a supposed, unproven Flynn connection, yet no mention of Hugh Wilson.
At the time Wilson and Strouse began their work on the South course, it was reported that the course had "no artificial hazards", which usually meant bunkers in the parlance of the time.
I'm sure Sean Arble would have loved it before Wilson and Strouse screwed it up!
Given Wilson's humble low-profile style, I have very little doubt that he worked with Strouse (and probably brought Flynn over as well) to help Strouse negotiate some of the realities of actually trying to work with the Willie Park plan once trees were felled and construction began.
However, it also seems that this would have been a very informal arrangement.
What would be interesting to determine is if Wilson was ever a Philmont member!
