I heard that he now plays on his Custom Meinl Weston F or Eb tuba. Not 45slp, I think.
Ask Roger Lewis, he knows better.

When I saw him perform several years ago, he used the third valve in lieu of the 1-2 combination, which I gather is typical in Europe. That would necessitate a different tuning strategy. At that time, he had a 5-valve 45SLP (though I can't remember if the fifth valve was on the right thumb or the left forefinger), and a tuning trigger for the left hand that actuated the second-valve slide. And he used that trigger, too.

Sure this is a Meinl Weston 46 RSP (Roland Szentpali signatured modell F-tuba) At the right hand is a trigger for 2nd slide, at the left hand there is two more valves for a TRITONUS valve and a QUARTER STEP valve...believe me!

Still confused (but not quite as bad!).

Here's a guess:
Here's a fingering chart for Grontiz tubas that could be optioned with a 3 whole tone slide (tritonus) what was changeable to a 2 whole tone slide (old Miraphone, sharp 2+3).

TRITONUS = 3 steps = roughly equivalent to valves 2+4

I'm guessing the 6th valve is either:
A) a flat half step (and the person you quote is mistaken)
Or
B) maybe that person you quote is correct and that shorter valve helps fix some of the wierd notes in that system. However, half the length of an F tuba's second valve is VERY VERY short, so I would be quite surprised if that is the case.
