This is my first posting since joining today (1/23/21). Thanks for referring to my 2018 AMERICAN PIANO CONCERTO COMPENDIUM book. I wish I had all this information for Nicholl back then, but I will make use of it. The notes on the Concerto were very helpful and I hope the full score can be found eventually. Let me know, please. Though my book covers 1869 to the present, and the big year was 1936, thanks to the WPA, there were many composers (and I have 1,056) who were still writing in the big Romantic style well into the 20th Century - primarily lesser-known composers, because the famous composers were busy writing in various contemporary styles.
