その結果，高精度の電子顕微鏡によって従来「平樺巻」とされてきた青柳（Ｈ‒46‒39）が，樺ではなく籐ないしカラムシのような蔓を巻いていたことが判明し，仏像の姿に成形した錘を頭部に挿入した龍笛があることが判明するなど，従来の調査では得られない成果が多々あった。一方，付属文書と笛本体が一致しない例もあり，笛が入れ替わった虞れも考えられる。たとえば能管の賀松（Ｈ‒46‒53）は，付属品や頭部の頭金の文様から，『銘管録』に載る「古郷ノ錦」ではないかと推測される。いつの時期か不明だが，コレクションの実態が混乱したようである。時期は不明だが，紀州徳川家のコレクションは少しづつ散逸してきた。その事実と照らし合わせながら，今後さらなる調査が必要になるであろう。, Among the musical instruments of the heirloom of Kishu-Tokugawa Family, 27 pieces of Ryuteki/ Nokan in total owned by the National Museum of Japanese History were investigated through close observation and radiography.
Observation by a high precision electron microscope revealed that vine such as cane or calamus instead of birch was wound around Aoyagi (H46-39) , which had been considered to be “Hira kabamaki,” and that some Ryuteki had a weight formed into a Buddha statue inserted into its head. This investigation produced many such new findings that had not been revealed by past research. There was a case where the pipe body did not agree with the accompanying document, and there is a possibility that the pipes changed places. As an example, it is inferred that the Nokan called Gasho  (H46-53) is the “Kokyo no Nishiki” mentioned in Meikanroku, judging from the accessories and the pattern of Kashiragane ( decorative end cap) at the head. The specific time is not known, but there seems to have been confusion over the actual status of the collection. Since some point in time, Kishu Tokugawa Family's collection has been scattered and lost gradually. Further investigation is needed to check against the facts.},
