* Ultra Sonic Cleaning (She has a tank large enough for a 6/4 tuba)
* Bell repairs (remove crease and make bell more symmetrical)
* Misc dent work (whatever is reasonably easy to reach)
* Add a B&S thumb ring (picture below)
* Evaluate whether to replace the Dubro linkage with proper mini-ball or uni-ball linkages

Crease in bell near patch.
B&S Thumb Ring
I'll post additional pictures after it is back from the shop.
