Concerto for French Horn no. 1 in D major, K. 386b / KV 412: I. Allegro

Caution with poorly documented recordings suggested.
This work is a (catch-all for unknown completions) and for the (Süßmayr completion).

The Süßmayr completions were the standard practice until the following book was published:
author:Alan Tyson, Mozart: Studies of the Autograph Scores, Cambridge, MA: Harvard University Press, 1987.
For releases made prior to 1987, in the absence of any evidence to the contrary, we can safely assume that they followed standard practice for those times. And used the Sussmyr completions.

However for releases between 1987 and the date when Tyson' discoveries became universally accepted, for releases whose date is unknown and possibly after 1987, and for poorly documented post-1987 releases there is the possibility that an unknown completion is not a Süßmayr completion.
Using this work for such releases could create erroneous data.
