This is an old Noh flute. I received it as a gift, a Noh flute made by Ranjō, and had it repaired by Mr. Ranjō a few years ago because it was damaged. It has been stored since then and is in beautiful condition. Although I didn't purchase the flute directly from Mr. Ranjō, he accepted the repair, so I believe it is authentic... However, there are no markings, so I would like to sell it to someone who can judge its authenticity from the images. Thank you very much.
