Initially piecing together a few sources (I don't see Schneider's symphonies listed on IMSLP), symphony appears to date from early 1820's. Amazon USA shows this cpo release for Aug 2.

From the blurb:
Schneider's Symphony No. 16 displays majestic chords, and its movements of song character win over listening audiences with their charm and naturalness while also offering their share of surprises, mirth, and high spirits. In contrast to his symphonies, which all remained unpublished and were more frequently performed only in Dessau with the composer as their conductor, his overtures for a time enjoyed great popularity far beyond his home region. Apart from his opera preludes, Friedrich Schneider wrote a total of twenty overtures, three of which are heard here.

I have found the Symphony No.17, an earlier cpo release, completely unmemorable, but the oratorio Das Weltgericht is quite an impressive piece of early romanticism.
