In the parts a few wrong notes were corrected in these scans:
Cl I Andante (measure 110): B, not C
Cl II Finale (measure 183): G, not rest
Hn I Finale (measure 222): D, not E
These mistakes are already in the first edition (Artaria) and were never corrected in the various editions by Breitkopf & Härtel, but see e.g. the new critical edition by Henle (2008):
Beethoven - Chamber Music with Winds, Ed: Egon Voss (HN4171/4172).
Page 2-3 of Cl I were distributed over 3 Pages for slightly better pageturns. User: Kalliwoda
