Tom:
Sadly, we do not have Ross' original plan.
However, we do have a plan drawn up by Chick Evans' golf architectural firm of the course as it existed in 1932. Chick's firm was hired to draw up a plan that took into account the widening of 87th Street by Cook County. 87th bisects Beverly and was, originally, basically the entrance to the club. Chick made some suggestions that weren't feasible with the day's equipment, and the first tee ended up getting moved forward and the ninth green was replaced, since it was originally in what is now 87th Street.
The course that Chick drew up was Ross' course, which 2 years previously had hosted that National Amateur.
Chick, btw, won the 1910 Western Open at Beverly under match-play.
