Op.16 may be a misidentification of the Introduction, Scherzo, Intermezzo, and Finale recorded on a Koch-Schwann CD (and which I'm uploading from BSB) though the key is a whole tritone off... or there may be two opp. 16. The Donemus PDF may provide clarification; haven't looked at it lately.

But the PDF as a whole I do not doubt is copyrighted or I would simply rehost it myself somewhere...) Eric 05:56, 17 December 2010 (UTC)
