Thank you for viewing! I purchased this last year, but I am selling it to buy another instrument. After purchase, I stored it in its case. It was only used once. The 1st valve lever became stuck during storage, so I had it repaired. Key: Bb/F Bore: 11.9 mm Bell Diameter: 315 mm Material: Brass Finish: Silver-plated Design: Detachable bell Accessories: Case, mouthpiece *Oil is not included Please feel free to comment if you have any questions m(_ _)m
