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 1926 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.

This is his first published violin sonata, but there is also a violin sonata in G minor, GP 49, from 1901 (recorded on Naxos and ASV.)
The 1910 version's 2nd and 3rd movements had tempo headings "Slow and Sombre" and "Allegro molto vivace" (and were fairly substantially different from the corresponding movements in the revision of 1915- revised at least slightly in 1920 and 1945 - published in 1921. Comparison is made possible by the recordings of these two movements on a Naxos CD; in GP 124 (1910) they were very different music.
