earlier Fountains performances edition(s)/sheet music: 1916 - 1993

[bloke]

Prior to the 1994 Kalmus edition (that everyone apparently uses, today), what edition (original manuscript...?? Ricordi...?? someone else...??) was read, and was the piece performed very much, outside of Europe?

(so here's Von Karajan's 1977 recording with Berlin: https://www.youtube.com/watch?v=eGZ9oslaeak )

As a high school student, I play both "Pines of Rome" and "Roman Festivals", so the answer to this question is obvious: YES.

Also, I have noticed that the IMSLP scan is wiped clean of this, but my older version (obviously, the very same edition/plates/scan/whatever) states,
"Edited by Clinton F. Nieweg and Nancy M. Bradburg"...surely related to the information below, that I found:

In 1993, Swiss conductor Adriano founded the Respighi Society in London in an effort to make Respighi's "life and works [...] better known and understood by the dissemination of accurate and impartial information.

(I'd provide the title to the article, but that might cause monitors to wipe my post away.)

side issue: 2021 is not 50 years past KALMUS 1994 Copyright, so what's this set of parts (with the publisher scrubbed from the scans) doing uploaded to IMSLP?

all above related to this:
I believe it would be interesting to be able to view an earlier edition.
