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.

A performance of a quartet- this one?- by Gibbs reviewed in the Musical Times in June 1920 (Volume 61, June 1 1920, page 390) specifies that it was not the premiere. Revista musicale Italiana also mentions a performance. (When were first two quartets written and what were their performance histories?...)
"Proxime accesit Carnegie Prize 1919".
Earlier quartets by Gibbs according to external link:
Also several later quartets (pastoral quartet op.41, A major op.73 - recorded, G minor "miniature quartet" op.74 (both 1933, published), also String Quartet in C op.95 (1940), String Quartet in G minor (Kenilworth), Op 99 (unpublished), String Quartet "No.6" in C op.118 (1947) (unpublished), A Simple String Quartet, Op 140 (1954, unpublished), String Quartet in E minor (1958, unpublished) ). So even not counting opp.1 and 6, arguably about a dozen or so string quartets.- Schissel
