I believe this is a violin part. I saw it at an antique shop a while ago and, feeling a sense of romance, bought it on impulse. I don't know much about its grade or anything... It's a hard, reddish wood, and it looks like a type of karaki (hardwood) material. If you have any questions or want to see specific parts, please ask in simple, easy-to-understand language, as if you were talking to a complete beginner (＞＜;). My experience is about the same as the time my wife and I did a two-person-kimono-wearing act in a used shop and moved a bow. The feeling of the sound resonating was interesting...!
