Just a comment that I hope will be constructive to your sale and maybe informative to other readers.
Could you detail the maker of your tuba and give other information like finish, high pitch conversion (?) and bell size, etc? It might help some people if you commented on the groups that you play it in and explain that 'Cavalry' isn't a make of Tuba but rather a layout which has, if I'm correct, piston valves which are front (horizontal) rather than top (vertical) 'acting'. I anticipate that there are other virtues in the design too but believe that that orientation is better if you're riding a horse, which maybe is where the term 'Cavalry' comes from, and found pictures via google images. I hope that the above is supportive.
