This is a Bach Corp. trombone and euphonium mouthpiece, model 6 1/2 AL, with a small shank. The engraving is in a small font, and it is said to be from a time when the quality was maintained. There is some plating wear on the shank. Please refrain from purchasing if you are looking for a perfect item or are overly concerned about condition, as it has been stored at home for a long time. Thank you.
