It is very unlikely that this work is public domain in the EU, or in any country where the copyright term is life-plus-70 years. However, it is in the public domain in Canada (where IMSLP is hosted) and other countries where the term is life-plus-50 years (such as China, Japan, Korea and many others worldwide). As this work was first published before 1923 or failed to meet notice or renewal requirements to secure statutory copyright with no "restoration" under the GATT amendments, it is very likely to be public domain in the USA as well.

Unearthed (well, from the Library of Congress and UFl collections), it seems, by Steven Isserlis and given its world premiere recording by Paul Marleyn and John Lenehan on Signum Records in 2004. Possibly not yet published except in this 2004 recording, however.
