Horn Mouthpiece Yamaha YAMAHA 27 Engraving: YAMAHA JAPAN 27 Overall, I believe it is in relatively good condition. There are some minor scratches from handling and shank wear, but I did not feel any hindrance while playing. *Please check the details in the images.* This model number 【27】 was discontinued over 30 years ago and is not currently available in Yamaha's horn mouthpiece lineup. Also, I think it is a rare model number that is not often seen. 《Specifications》 ・Inner rim diameter: 16.6mm ・Rim thickness: Medium ・Throat diameter: 4.5mm ・Capacity: C (Standard) ・Backbore: C (Standard) ・Rim contour: 3 ・Features: The rim is small, with a deep V-cup and a thick throat diameter. Good sound projection and volume are achieved across the entire range. Suitable for 1st and 3rd players in an orchestra. If you are looking for one, or if you wish to purchase it, I hope you will make a decision as soon as possible. *Due to the nature of mouthpieces, there will inevitably be minor scratches due to contact during instrument attachment, handling, cleaning, and wiping. Also, I have confirmed that these do not affect the performance at all before listing. If you are looking for a perfect item on par with a new one, or if you are particular about the details, please consider carefully before purchasing. We are selling it at a low price considering it is used, so we appreciate your understanding. Thank you for your consideration after understanding the above. [French Horn]
