This is a tuning slide (main tuning slide) for a Yamaha YTR-8335S trumpet. It has been gold-plated. The water key is also gold-plated. While there are signs of use and small areas where the plating has come off, the condition is good. Although the water key spring is not shown in the photos, it will be included, along with a new cork, using a genuine 8335 spring. Shipping is free. It will be sent via Yu-Packet Plus. Year-end and New Year's Holiday Notice: Shipping will not be available from December 31st to January 3rd. Thank you for your understanding. Thank you for viewing.
