Available here is this interesting old German music book:

Melodien zu dem Katholischen Gesangbuche von Moritz Brosig

Kapellmeister an der Kathedrale zu Breslau

(Melodies from the Catholic Hymn Book by Moritz Brosig

Conductor at Breslau Cathedral)

published in Breslau, no date but evidently mid-19th century.

Bound in with it are several pages of manuscript music.
