Fascinating, Neil
I have a reasonably educated guess that "Andy" could well be Archie Simpson, based on the research which I did for an article I wrote about him several years ago:
http://www.golfcoursearchitecture.net/Article/Archie-Simpson/1432/Default.aspx#.UxhxyYX1nIUArchie was one of the finest golfers in the world in the late 19th century as well as perhaps Old Tom Morris' most trusted architectural assistant, working with the great man on courses such as Dornoch and Cruden Bay. He worked in both England and Scotland as a golf professional and an architect and designed much of the back 9 at Royal Aberdeen as well as all of Murcar and many other courses in and arpound Aberdeen.
He moved to the US in 1911 to become the Professional at the CC of Detroit in 1911, and there are occasional references to him in the LA84 archives, both as an accomplised golfer and as the man who assisted Harry Colt in his re-modeling of the CCofD course in 1913-4, but after 1914, the references stop. The next thing we know about Archie is that he went back to Scotland in 1921 before returning to the USA spoon after, moving itinerantly from Illinois to Ohio to Illinois in the 1920's before disappearing again until his death, from "old age" in 1955 back in Detroit.
In writing the article linked above I was in contact with CCofD officials and they were very friendly until I broached the subject of:
1. How much of Colt's remodel was actually done by Archie, and
2. Why did Archie leave, and exactly when?
All I got from them was silence. Not more friendly correspondence saying something like "Sorry, Rich, but we just cannot find that information", but complete silence and no responses. I gave up after 2-3 tries and then wrote the article.
I have a theory as to why Archie seems to have been airbrushed out of CCofD's publicly available collective memory, but it is just coincidental speculation. I have more confidence in stating that Archie's relationship with CCofD went sour at sometime after his arrival in 1911, and that if this is so, the pseudoymous advertisement that you have posted would fit the facts and my speculations. That the advertisement was posted at the height of WWI also fits with its text of a man stranded in a place he longer wanted to be.
My thoughts, anyway.
