I'm glad to announce, that today I have published Joseph Küffner: Six Airs Favoris in three versions: CLEAN-urtext version, EDIT - with fingering, TAB - tablature and cue sized fingered score.
All three versions are prepared as print self-booklet and they are very reasonable priced. All three versions under this link: http://www.store.bergmannedition.com/volumes-of-scores
All six airs can also be bought as single sheets.
The original can be found in the Birket-Smith collection: http://www2.kb.dk/elib/noder/rischel/RIBS0459.pdf
