This work is likely not in the public domain in the US (due to first publication with the required notice after 1922, plus renewal or "restoration" under the GATT/TRIPS amendments), nor in the EU and those countries where the copyright term is life+70 years. However, it is public domain in Canada (where IMSLP is hosted) and in other countries (China, Japan, S. Korea) where the copyright term is life+50 years.

I don't know where the AK numbers come from.
AK = A/K = Archiv/Katalog. I'm not positive but I think it may be largely Eva Mantzourani's hard work...
Though if the 1955 or even 1965 score has A/K numbers then I'm mistaken (at least partially).
