Thank you, Juergen. It was a pleasure to listen to you, as I am currently working on this piece and others from Kuckuck. This quite an old thread and it is, perhaps, helpful of me to offer some new information to readers. In addition to the public domain facsimiles, e.g. Danish Royal Library, there is a modern Japanese edition in two volumes published by Gendai Guitar in Japan, (ISBN 978-4-87471-517-8 C3373 and 978-4-87471-518-5 C3373.) I purchased mine from Strings by Mail in the US. Given my poor eyesight, these were so much better than the poor copies of the facsimile editions.
