Sven, Ira,
I don't consider those plans detailed at all, at least not in design thought. I only saw one note that even mentioned how a slope would affect a shot, etc. It was mostly construction related, like how deep this bunker or that ought to be, what to remove, what to save. Not that I would necessarily expect it. A common thought on preparing any type of construction drawing is to give the builder what they need to build, not necessarily explain design thought, which the builder should take for granted....although as time goes on in the golf biz, builders question architect's intent and'/or substitute their own judgement in place, especially if they don't expect the gca to come around to check for a period of time and they need to get it done (or, they are passive-aggressive in nature, but I digress.....)
But, there is nothing on those plans to indicate any deep, deep thoughts. (unless you count deep, deep, bunkers as thoughts!
Ira,
As to those tongues, I have wondered the same thing. I believe green corners could be tighter in those days because they were all mowed by hand. I have also seen 50-60's era Dick Wilson and Joe Lee plans where the green edges and corners are much more squiggly and sharp than I have ever seen in photos. In both cases, I wondered if they really meant them to be built that way.
