Many thanks for this upload, Ilja. A "new" Van Gilse piece is always welcome.
Symphony 4 (composed 1915 acc. kb.nl, 1910-15 apparently more accurately?, cop.1916) btw has these movements if this hasn't been posted already. Source: www.kb.nl (Dutch Royal Library.)

(score published by Kistner of Leipzig, plate 10745.)
