Before and After: a humpback trombone bell! Lots of geometry issues with this one. Straightened out the bell. Removed the valve section to replace the broken and missing braces. Fixed the last technician's poor geometry dealing with the tuning slide. Removed the hand slide end crook to remove the dents that also affected the hand slide tube geometry. It also had a thorough cleaning. I love how Weight's Copper polish evens out the finish!
