This high end tuba has been modified so the leadpipe is off the horn. It actually comes completely off the tuba, which makes all those measures of rest counting nearly foolproof. You just think no sound, and no sound comes out. *when removable leadpipe feature is engaged*. The leadpipe is also "vented" and the water key has been "removed"
Just like Thein, bits of metal have been added.
...it is a Mirafone standard that wasn't fit to be a wall hanger.

So very, very ugly. Nearly all braces broken, the bottom bow pancaked completely flat in one spot (I am not kidding),

bell pancaked. Then bent backward, then sideways and possibly attacked by Huns. The trim sliced up, cracked up bell full of holes...not fit for a parts horn because of so few good parts.
However.... I did some fast, extremely crude work on it & got it back into the shape of a tuba.
The valves work fine & the 1-3 slides are OK ish. Could be better but nickel silver stuff. I thought more than once about taking the valves & scrapping the rest.
it doesn't sound completely unlike a tuba. If I hold the leadpipe & plumber's tape the water key hole, I can make tuba-like sounds with it.
The main tuning slide needs dent/alignment slide work with better tools than I have, it needs to be fixed to the horn & it needs a water key. I have it just flopping around right now so it will move.
$300
Or $200 and a tuba tamer type stand
or used blokepiece or Stofer mouthpiece.
Or you can suggest something via PM. If you are interested in purchasing or a partial trade.
