Yes. All the other notes (other than E/B) have open holes below them.
E/B is thus brought into line by the modification.

Don't know about this model, but a hole in the *bell* appears on some
German clarinets. I have a C clarinet with a defective E/B twelfth made
by Kohlert, but because the instrument sounds good, I didn't want to try
to correct the intonation by altering the cone at the bottom of the
instrument. (This adjustment also has an effect on the tone quality and
response.)

So, you may have been kidding, but I had a small hole drilled through
the bell and the tenon. If you need a non-flat low E (I did, on that
occasion), you rotate the bell so that the two holes coincide, if you
have time. (If you don't have time, you don't do it!) For playing
normally, the bell position is such that the two holes don't line up, so
the instrument behaves as it did originally.

Some German clarinets have a key to open and close such a hole.

Well, as I said elsewhere, it's a controversial issue. But my view is
that, although we can learn much from acousticians, some of them don't
understand our concerns. Some of the research on the effects of
changing various parameters like mouth shape, or instrument body
material, on the sound of the instrument says, for example: "this
difference of tone quality is negligible, because it is smaller than the
difference in tone quality between adjacent notes on the same
instrument."

As we players know, such a difference can be *huge*.

FWIW *I* think that vocal tract has an influence on tone.
