K.Anh.C 9.10 looks like a K6 listing, not a regular K. listing, but Abendruhe is nowhere to be found in the NMA online. (Possibly spurious work?... 1950 estimated date from search by text incipit. A work by the title "Abendruhe" by Mozart seems to have been mentioned and perhaps published earlier, but may have been a different work, with a different text, than this one.)
