No, it's in Eb. Like one of these:

That's what I was trying to do, and it may well have worked if I had been reading a part in the same key as the other part.
(Though all the tenor (?) clef bits in the trombone parts are not at all helpful to a trumpet player trying to play trombone parts on an Eb alto horn.
we can consider to do something for you.
I'm not asking you to, owing to the unusual nature of this instrument. It's apparently not much used outside British-style brass bands.
I'll take a stab at anything you can be bothered to transpose though. Most particularly Bb trumpet/Eb horn duets
In any case, I was mostly sharing my amusement at the realization that the duet and quartet arrangements are in different keys. If I had noticed that rather obvious fact sooner, it would have spared me a great deal of confusion, and ugly, dissonant sounds.
