Monette trumpet mouthpiece, RAPAV4 PRANA 88 19. This is a custom model that Adam Rapa used before Lotus. The rim size is about the same as a BACH 1 1/2C, the cup is about the same as a Bach D, and the throat is 19. In Monette terms, it's similar to a B3FS7 or B4. There are no scratches or dents that would interfere with playing.
