Canzona per Sonare No. 4 - Rob't King arr. - baritone part?

[bloke]

EDIT:
Thanks very much for helping me !
As it has now been determined that the "tuba" part is actually a sometimes-double of the "baritone" part (only four actual parts), the trombonist in the quintet (who is also playing the entire Poulenc Brass Trio on this same quintet recital, and could sorely use a break) has - rather than me - decided to sit out this Gabrieli piece, and have me cover it on the baritone.

As with many Robert King arrangements of Renaissance period music, I've been sent a "tuba" part (after all, I play the "tuba") to play with a brass quintet.

My experience with many of these "tuba" parts is that they are very low-voiced, really only intended for expanded ensemble, and double King's written "baritone" parts at the octave...often with some of the (bass/5th) "baritone" part omitted (i.e. rests) in the "tuba" part.

...so I'm just checking, please:

IS there a "baritone" part for this arrangement, and should I be playing it?
If my suspicions are correct, would someone be willing to help me out (in order to improve an upcoming performance) ?

My email address is in my signature. Thank-you in advance for helping...assuming my suspicions are valid.
