Tenor Saxophone Mouthpiece Berg Larsen 105 3 Offset M Body only. The "M" stamp, offset to the side, indicates vintage. I've treasured this mouthpiece for many years for its ease of sub-tone playing, along with the gritty sound of Sonny Rollins. The "3," the thickest sound, is rarely seen, so many of you may be looking for it. There are no issues with use, but it is a used item, so please understand and purchase if you can judge from the images. Returns are not accepted, so please check carefully. #Larsen #Belglasen #Tenor #saxophonemouthpiece
