I own a copy of the score in subject (Ricordi nr. 132187 - vocal score with piano reduction). The work was composed in 1880, however it was first published in 1951. The Ricordi score shows 1951 as its copyright date, and there is no other name on it than Puccini's name (no editor name, no name of the author of the piano reduction). As this work was originally intended as the final exercise for Puccini's conservatory diploma, I guess that the piano reduction is by the composer itself, as it was probably required to submit the work to the conservatory. So I think that this edition should be regarded as an urtext edition, with no significant content added by others.
I think this work is PD in Canada and EU. Puccini died in 1924, so all terms related to the composer's death, editio princeps (if ever applicable - first publication of 1951 occurred much earlier than 70 years from Puccini's death), and protection of urtext editions appear to be expired. Is this alright? Does anybody have any different information concerning the author of the piano reduction? I googled and searched worldcat extensively, however I found nothing.
