Morgan RM-15 mouthpiece for B♭ clarinet, designed by noted mouthpiece maker Ralph Morgan. The RM-15 is generally associated with a warm, centered tonal character, comfortable response, and good projection, making it suitable for classical, concert-band, and general-purpose playing.

This example is made from hard rubber and retains its original Morgan and RM-15 markings, though the engraving has become faint. It shows considerable exterior oxidation and discoloration, along with scratches and other cosmetic wear from use. The tip and rails appear intact, without an obvious crack or major chip. The tenon cork is present but shows wear. The facing has not been professionally measured or play-tested. Includes the Wind & Reed storage pouch; no ligature or cap.
