This is a Noh flute (能管). It's a genuine instrument. It produces a soft sound (compared to plastic flutes). It can also produce the "hishigi" sound. It does not have a mouthpiece (頭金). You are welcome to add one yourself, but it doesn't significantly affect the sound if you don't. It's not an old instrument. Please feel free to ask any questions you may have. Thank you for looking.
