Benge Trombone Mouthpieces (now discontinued) were made in the USA & use the same numbering established by Vincent Bach in the 1920’s. The Benge Trombone Mouthpieces we have left in stock are high quality copies of  Vincent Bach Trombone Mouthpieces. They are old stock in perfect condition but the boxes they are supplied have become a little tatty in storage. This of course does in no way affect the integrity of the mouthpiece itself. As a bonus they come supplied with a rubber mouthpiece pouch which offers good protection against picking up dents. Also included is a mouthpiece cleaning brush so you can keep the throat clear of debris.
