This listing is for a "Sounds of Woodwinds" barrel for Bb soprano clarinet. This is a 'ringless' barrel that is made out of Ebonite (hard rubber). It is stamped "HRR" in the middle of the logo, but I'm not sure what that refers to. The only other marking I see is a small "6" on the back. I'm guessing that is in reference to it being 66mm in length.
This barrel is in excellent used condition. There are no cracks, chips, or other damage, and no scratches. It is not faded or discolored.
