I think this is a digitized copy of the St. Basil's Hymnal 1906 edition. in the PDF link at the top of the page. http://tcmf.homestead.com/StBasilHymnal.html
The hymnal is listed here as http://www.hymnary.org/hymnal/SBH11906
Hope this helps.

14th edition not 10th
Looking at it again it looks to be the 14th edition with an unknown publication date. So another "new" hymnal
