This is a very nice Gale Hollywood hard rubber mouthpiece for bass clarinet. The inner workings of these pieces features deeply rounded inner side walls with a very well defined circular throat. This piece is perhaps ideal for the saxophone player or doubler looking for something more free blowing in comparison to the typical bass clarinet mouthpiece.
The outer body of the piece is in good shape showing some normal cosmetic wear. Most just standard playing character and a few light scratches, nothing too serious. Much of the inking around the Gale stamps is gone but you can clearly still see the imprinting.
The tip opening of this mouthpiece measures .075”.
