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 have been unable to identify the model number, so I am 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 Sound has not been tested, and operation has not been confirmed. Therefore, this product is being sold as-is, with the assumption of maintenance, and is considered to be in a junk condition. There is overall wear and tear, and discoloration is visible 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 a wind orchestra or brass band in their school days and want to start again after a long time. - Those looking for home practice or sound-testing purposes. - Those considering a used instrument with the assumption of maintenance and adjustment. - Those looking for a sub-instrument or spare instrument for schools or local organizations. Due to my lack of specialized knowledge, I may not be able to answer detailed questions regarding specifications and adjustments. Please prioritize the photos for the condition, and the item is sold as-is with no returns accepted. Please consider only if you understand that this is a used and aged item. #YAMAHA #Yamaha #TenorHorn #BrassInstrument #WindOrchestra #BrassBand #UsedInstrument #AsIs #Junk #RequiresMaintenance #SoundNotConfirmed #WithCase #SchoolEquipment #HomePractice #silverbrass #tenorhorn #usedinstrument #bandinstrument
