I was barely able to find enough that I could manage to remove without resorting to getting into the expanding bows of the instrument.
With a shallow mouthpiece (and/or small shank) it will now play to about A=442 (slide all the way in)...
...with the typical (model 84) flat open D-natural and flat 8th partial (top-of-staff) B-flat.
Rotors 1, 3, and 4 are marginally acceptable (air leakage resistance).
Rotor #2 is unacceptably leaky, but the instrument will play, and mineral oil (down the 2nd slide tubes to the rotor) slightly improves playability.

dude...someone wrote:I don't work on substandard instruments.
I may very well consider yours to be substandard (not necessarily in workmanship, but maybe in playing characteristics
, but I'd probably be willing to work on it.substandard instruments:
Hey...people can play tunes and have fun playing them on 3rd-world-country-made guitars...and "pretty good" guitar players seem to me to be way more picky about guitars than "pretty good" tuba players seem to be about their tubas.
the quality of my finish touch-up work: B? B+?
aligned with the amount of money I felt was the limit of what was appropriate for the customer to spend to address these-and-other issues (again, based on overall build quality and my opinion of potential playability).
