Old books for musicians and beyond

Four ancient books: 1856, 1901, 1941, and one without a specified year, but approximately early 20th century. Three books with musical notes and texts in German, and one in pre-reform Latvian "Stories from the history of the Christian congregation," authored by W. Plutte. Condition is normal for books of this age, but the oldest one still requires restoration, although all pages are preserved. Price for all together.
