This is a Giardinelli trombone mouthpiece. The size is 6D, for a small shank. This mouthpiece is becoming difficult to obtain due to the discontinuation of production by Giardinelli's acquisition. There are some areas where the plating is worn, as well as scratches and scuffs on the rim, body, and shank. There are no major scratches or dents that would interfere with playing. Please refrain from comments asking for a price reduction. Immediate purchase is OK. If you are interested in used or new mouthpieces, please search for "net brass". net-brass.com
