Thank you for viewing. Tenor Horn This is a brass instrument with a 3-piston valve system. The mouthpiece is stamped "YAMAHA JAPAN 9". There are also markings on the main body, but I haven't been able to identify the model number, so I'm listing it as model number unknown. Accessories include a hard case (with deterioration) and one mouthpiece. The case shows signs of aging, so please consider it for storage and packaging during shipping. No instruction manual or warranty is included. ■ Product Features and Condition I haven't played it to produce sound, and I haven't checked its operation. Therefore, this product is being sold as-is, assuming maintenance is required, and is considered to be in a junk condition. There is a general feeling of use, and discoloration can be seen on the inside of the bell. There are dullness and scratches on the plated parts. On the other hand, the pistons move smoothly, and there is no feeling of sticking. Please understand that there are changes due to aging. This instrument is more suitable for: - Those who have experience in brass band or concert band in their school days and want to start again after a long time. - Those who are looking for an instrument for home practice or sound production. - Those who are considering a used instrument on the premise of maintenance and adjustment. - Those who are looking for a sub-instrument or spare instrument for schools or local groups. I do not have specialized knowledge, so I may not be able to answer detailed questions about specifications and adjustments. Please prioritize the photos for the condition, and the item is sold as-is with no returns. Please consider this item only if you understand that it is a used and aged product. #YAMAHA #Yamaha #TenorHorn #BrassInstrument #ConcertBand #BrassBand #UsedInstrument #AsIs #Junk #RequiresMaintenance #SoundNotConfirmed #WithCase #SchoolEquipment #HomePractice #silverbrass #tenorhorn #usedinstrument #bandinstrument
