Karl:
I've identified North Shore in C&A in NA as a CM&A course. It is noted as "just formed" per the CT 3/9/1922. It was under construction per multiple CT articles in 1923 and opened in May 1924. Also CM&A is identified as the architect in the October 1924 issue of Golf Illustrated which carried a lengthy article on the new course.
The CM&A firm was short lived as Colt himself struck MacKenzie from the masthead in January 1922. For the record any course in the US by CM&A, C&A, and CA&M(Morrison) was designed by Capt Charles H Alison. The club website of 2018 as well as Cornish & Whitten confirm the Alison pedigree and opening date. Based on the above and additional construction timing articles, I listed NS as designed in 1922, in construction through 1923, and opened in Spring of 1924.
As part of my research Chick Evans in a 1914 Chicago Examiner article notes that Tom Bendelow designed a NSCC 9-hole course of 2,551 yards on another site. So Bendelow was involved with the club much earlier and perhaps did a review of the new site to confirm its acceptability for a course. Your article suugests that possibility. Bendelow often reviewed land gratis for clubs from the turn of the century through the '20s with the possibility of doing the design work or selling clubs and balls to the members for Spalding.
I have found no drawings by Alison regarding the NS club and would dearly like to see that "smoking gun." There have been too many clubhouse fires, superintendents who took drawings with them, committee members, etc. So if a club has their Alison drawings (or in Old Elm's case their Colt drawings) it's a small miracle. Even OE's Colt drawings, proudly displayed at the club, are copies today.
