George - Looking at Cornish & Whitten I see that Riddell's was Devereux Emmet 1922 (solo), Belmont Hotel & Club 9 holes 1924 & A9 1928 also solo by Emmet.
Your comment about taking over for a busy Raynor might have applied at Belmont and perhaps worked with Banks at Mid Ocean in the early 1920's. Banks died in 1931 after "laying out" Castle Harbor.- who finished that in 1932 ?
By the way, Joe, a Tom Stewart mashie niblick just sold on ebay for $338.33 which was owned by someone in the United Kingdom who labled himself "Far and Sure", a member of Ebay since 2000.
