[Trombone-l] Arban's in Treble Clef?

[Bonemaster]

MTC: Really love my Arban's original.

Trying to convert a young Eupher to 'bone...he's happy right now, I guess
his age of enlightenment has not been reached.

He's got no method book from which to work an develop skills. Was the
original Arban's printed in treble clef for baritone/euph? Anyone know where
I can get a copy?
Is there a better 'bible' for baritone/euph TC than Arban's?
Thanks a lot,
