Thank you for viewing! (^-^) This is a rare model, a Yamaha B♭ clarinet, SEV-F. The key posts are pink gold plated. The barrel and bell are engraved with "F". This is a selected instrument by Kazuo Fujii, who was involved in the production of the SE series. All registers play without issue. I think it's in good condition for its age. For price negotiations, please offer your desired price. (._.) ※This product is not an SEV master.
