Catharinus Elling - Concert Piece for Flute and Orchestra

[Justin]

I have just uploaded an archival radio recording of this "konsertstykke for fløyte og orkester" work by Elling. Could I use someone's help in trying to hunt down a composition date for this as well as any opus number?

A flute/piano reduction seems to have been published as part of a collection in 1930, and I believe it lacks an opus number, but nothing more beyond that at the moment?
