Thank you for viewing. This is a Buffet Crampon MOENNING barrel, 64mm. I previously acquired this here. It's an "S barrel" purchased from Sato Techno Music for a Prestige A clarinet. The Buffet Crampon logo is fading as shown in the photo, but there are no stains or scratches. * The engraving says 65mm, but it has been shaved down to 64mm by Sato Techno. This is ideal for those who have trouble with low pitch in winter. * Please note that this is a used item, so no returns or exchanges are accepted. There is no original outer box, so it will be protected with bubble wrap for shipping. I will ship it quickly, so please consider it.
