Ralph,
Maxwell worked there in 51-52. It was his last project, and I don't think he lived to see the greens grassed.
He was hired to do a few new holes, but later was asked to rebuild a few greens as well as part of the project.
The bigger question about club is whether its Langford (their belief) or Stiles (Ron Whitten's belief as he has an ad from Stiles touting it as one of his designs)
Also, I have seen some aerial photos from the 1960's. There were some cool old timey stuff that was taken out, particularly what appears to be a reverse slope dell/punchbowl par 3.
I have a copy of the Dave Bennet report at the office, but I don't think he did much there other than that report. As I recall, OCC once had a pro who considered himself a designer, and I believe he did a lot of the work there over the fifties and sixties, uncredited.
