Purviance Trumpet Mouthpiece

It is well made like all of Bob Reeves products. I like that the blank is more like the original Purviance mouthpieces. I bought it as a backup to my early 80’s 5*k4 that I recently changed to for commercial playing. It is slightly different in resistance and sound then my older piece. I can bring them to the shop for comparison when I get back down to So Cal.
