I’d never heard of this work, much less the composer. I’d love to perform this sometime! I think it was originally for French horn but perhaps included an “or English horn” on the front page. I’ve not seen the music since it’s not available on imslp in the US yet and I’m careful not to download things that are still under copyright.
