Sean -
Regarding Woking, I have not come across any references to Huntercombe as an inspiration for changes made there, including the c/l bunker on the 4th. If you have found references, I would love to see them. There are, however, any number of suggestions that Low and Paton were inspired by features at TOC (and other links courses) in redoing the 4th at Woking, in building the 'Johnie Low' bunkers and other changes on the course.
Based on what I've seen in mags and books, Huntercombe didn't get a lot of attention at the time it was built or in the decades that followed. That Darwin did not include it in his book is consistent with that. Rightly or wrongly, Park does not seem to have been highly regarded by Low, Darwin, Colt and others. A further sign of that was the muted response to Park's work at Sunningdale. By contrast Colt's revisions a few years later were widely praised.
I have played Huntercombe. I saw it more as a culmination of an older inland style course (and a very good one at that) than as a course that pointed to the dramatic changes that were then overtaking architecture. I tend to agree with Simpson, Mack, Darwin and others that Woking should be seen as one of the main revolutionary courses of the era. I don't think Huntercombe belongs in that group.
