This listing is for a Bb clarinet barrel. It does not have a brand name on it, nor any other markings. This barrel is made of plastic. It is 66.5mm, which is more or less standard length.
This barrel is in good used condition. There are no chips, cracks, or other damage. It does have minor scratching/scuffing consistent with normal use. There is some minor oxidation/plating wear on the tenon rings.
This should be compatible with most Bb clarinets. As is always the case when fitting a different barrel, you might need to adjust or replace the cork on your clarinet's mouthpiece and/or upper joint tenon for proper fit with this barrel.
