Was Desmond Muirhead alive back then??
Seriously, that bunker complex that seems to be a "hell's half acre" sort of thing on the par five is unique to my eyes.
At first, I thought it had to be something by Dev Emmett, but I'd bet even money that Tillinghast was there. In particular, those elongated greenside bunkers are something I've seen him do a lot of.
No idea on the course, but that's the first place I'd check. Rick Wolffe...did Tillie do any work out on the end of the island?
