[Avodah] Tefillin on Rosh Chodesh

[Zev Sero]

Another datum:  At least some Italian shuls say Keter in Shacharit and
Mincha as well as Musaf.  (Machzor Livorno gives both Keter and
Nakdishach and prefaces the latter with "some say this in place of Keter";
the Italian shul in Y'm says Keter.)  Do they remove their tefilin before
chazarat hashatz every day?  I assume not, so they probably don't think
it's a problem to say Keter in tefilin.  Given that, does anyone know
whether they keep their tefilin on for Musaf of Rosh Chodesh?  It would
make sense that they should, and Machzor Livorno doesn't mention anything
about removing tefilin, but I don't know.
