The impresario : copyist's manuscript, 1786?

Copyist's manuscript of the full score of the Singspiel; late eighteenth or early nineteenth century.
The copy follows the autograph manuscript very closely; differences noted include: the brief orchestral ritornellos that introduce the Arietta and Rondo, which are not found in the autograph, are included here; the tempo for the Sinfonia is Allegro assai in the copy, but Presto in the autograph (although Mozart's original tempo, crossed out, was Allegro assai); in m. 94 of the Terzett, the two turns in the vocal part present in the autograph are missing in the copy; and the timpani part for the Schlussgesang (which Mozart wrote out on a separate leaf) is lacking in the copy.
