front cover does not have diacritics. Schott items with plates in the 1200s have been estimated to have been published around 1819 or so- how accurately?... later items with plates above 1500 are believed to have been produced around 1822 or so (again, not sure how accurately). Still, suggests a date sometime around 1820 or 1821 if so- plate 1325.
