This is an oversimplification.  If it is transposed it is transposed.  If a
piece is in Eb and the trumpet/horn parts are for Eb trumpets/horns then
they won't see a key signature because they are in C.

What I'm about to say is likely also an oversimplification as well, but
less so.

Trumpet and horn parts written before the widespread use of valves were
written, in effect, for bugles.  The key of the instrument to be used was
indicated on the part.  Naturally, these parts would appear to be in C for
the player (plus accidentals).  To change key, the player had to change the
'crook' which was a removable loop of tubing which was the correct length
for a given key.  Once valves came to be the rule rather than the exception
things changed.  Trumpet parts in particular become more complex and
melodic (compare a Mahler trumpet part with a Beetoven trumpet part).

For pieces written after the Romantic period it is much simpler.  Trumpet
parts are transposed completely but the "key" of the trumpet is indicated
on the part (Trumpet in C, Trumpet in Bb, Trumpet in D etc.).  Also, a
player may prefer to play C trumpet most of the time and simply transpose a
Bb part in his head and play it on a C trumpet.  This is one of the things
modern trumpeters have to know how to do, and it is how they deal with the
older orchestral literature written for different keys of trumpet.  It is
common for modern players to play a 'Trumpet in A' part on a C rather than
a Bb instrument as it is easier for them to transpose to the next line or
space than by a half-step.

Modern horn parts are generally written for the F Horn.  That is, they
sound a fifth lower than written (or read a fifth higher than sounding).
Horn players have the same transposition duties as trumpeters when it comes
to Romantic, and earlier, literature (perhaps some later material as well).

Trombones:  Sound as written.  This goes for Bb tenor trombones, Eb Alto
trombones, or contrabass trombones in F, Eb, or BBb.  The one exception is
treble clef trombone parts in British Brass Band music which is transposed
and sounds a major ninth lower than written (like tenor saxophone and bass
clarinet).

Euphonium/Baritone/Tenor Tuba: When written in bass clef it sounds as
written.  When written in treble clef it sounds a major ninth lower.  Some
Richard Strauss pieces (Ein Heldenleben, Don Quixote) have parts written in
Bb bass clef so that the part sounds a step lower than written in bass
clef, but this is the exception.

NB-tromobnes and Euphs/Bars/Ten Tubas:

The trombone that people think of as a regular trombone is in Bb as is the
Euphonium.  The posting regarding the scales for four instruments mentioned
"trombone in C".  This is both right and wrong at the same time.  The
instrument is in Bb.  Its fundamental note is Bb with the slide closed but
the player thinks of this note as Bb and not C.

Tubas:  Sound as written.  Tubas commonly exist in BBb, CC, Eb, and F but
they all sound as written.  The tubists learn different fingerings for each
instrument.

***************************
Saxophones and jazz notation:

Saxophones are all transposed.

Bb soprano sounds a step lower than written (like Bb clarinet).
Eb alto sound a maj. sixth lower than written (like alto clarinet).
Bb tenor sounds a maj. ninth lower than written (like bass clarinet).
Eb baritone sounds an octave and a maj. sixth lower than written (like
contralto clarinet).

Trumpet is assumed to be in Bb and is transposed to sound a step lower than
written.

Trombones sound as written.

The musicians know what note they're sounding.  When dealing with the
conductor it is simply a matter of adding the word "sounding" or "written".
 Scores exist in both forms.  Some have all instruments' parts as they
appear and others are all in C.  The conductor should know which he has in
front of him.

But this whole discussion is how to deal with it in PMX.  Finale, for
example, has the ability to render a score on-screen in C and you can
assign each part a transposition for the parts.  This is handy if you use
MIDI input to speed things along as this is all in C.  PMX is itself a
speed-up for TeX input so this is not as relevant as it might otherwise be.

To me there are two choices.  You have a score with all the parts
transposed as the players see them, or you have a score in C and the
players see transposed parts.  The first one is easy.  Each part gets its
own key.  The second solution would require scor2prt to do something with
each part.
