Gelli cites the Deutsches Paukbuch family under Heinrich Roux at Jena/Mauke with an 1857 witness, a second edition notice of 1858, and a further 1867 witness. The separate local work 1911 is a truncated by-product of the same cataloguing family and should be treated as redundant rather than as a distinct work.
