Pearl, a well-known manufacturer of percussion instruments and flutes. This model is the NC-96N, made entirely of sterling silver. The joints are in good condition and can be assembled without any problems. The head joint cork should probably be replaced, but it has been temporarily positioned. Some pads show damage. I was able to confirm sound production up to Low C, but there are some notes that are difficult to produce, so I recommend replacing or adjusting the damaged pads. The movement of each key is not a problem. Key oil has been applied. There is some slight wear and tear, but overall, I think it is in a clean condition. It would be good as a collection piece, or it would be good to have it properly adjusted and used! Please consider it. m(__)m
