Thank you for viewing. I am selling this because I no longer use it. Can be attached to current Alessi models and 5GNY. Please check the condition from the photos. There are some scratches on the support. ↓Overview↓ Shires For tenor/bass trombone Seamed tubing Tuning slide Gold brass ※What is a seamed (rolled tube) tuning slide?
