Ronald, and Mike;
I don't have enough direct experience with the Gordons to instantly recognize one of their courses, however:
1. Look at the bunker shapes; there appear to be about three different styles here; one in the V-shaped piece of the property in the lower left corner, a second in the squiggly shapes towards the topmost holes, and some flower-shaped ones towards the center.
I am thinking more of the bunker shapes in this bottom "V" as more consistent with what I have seen from the Gordons, sort of "roundish" like Flynn but laying less soft on the land, or less carefully placed, as Flynn's features do.
2. Many of the holes, in particular the longish par 5 more or less in the center of the property have a long, lean appearance. Similar to a few of the holes at Saucon Valley, Indian Valley, Hercules/Delaware Nat'l and Deerfield.
Consider the 1st at Deerfield compared to this hole--it's a long hole, and the dogleg comes very "late" in the hole (I know this is a bad way of putting it, but I think you understand what I mean); the dogleg isn't able to be carried or cut from the tee.
These are just a few thoughts currently.
