This is a Monette trumpet mouthpiece. The model number is Prana RAPA V4 88. The size is between a Bach 1 1/2C and 3C, with a cup that is slightly shallower than a Bach, and a ball-shaped cup. The rim feels soft on the mouth, but the inner edge is sharp, providing a good response and making it less tiring to play. It has the characteristic Monette sound, and when played strongly, it produces a very brilliant and powerful tone. As the photos show, there are no dents or peeling.
