This is a barrel for the Selmer Privilege A clarinet, a flagship model. It worked without issue on Yamaha B♭ clarinets and Buffet Crampon A clarinets. I received it as a gift, so I don't know how long it was used. Please refer to the photos for detailed condition. My first impression was that it's very easy to articulate with. Also, the sound didn't crack, no matter how hard I blew. It's a barrel that allows for a light and agile sound.
