Thank you for viewing. This is a mouthpiece for a YAMAHA trumpet, made in the early 1970s. It's a standard model loved by a wide range of players, from beginners to experienced musicians, and is characterized by its bright, clear tone and easy-to-play cup shape. It's also ideal for practice or as a spare. It shows considerable signs of use, but there are no problems with its functionality. It has been sterilized by boiling. Please feel free to contact me if you would like additional photos. Thank you.
