Sorry to comment, but did you check the RISM doesn't describe the
contratenor (which IMO would be a better description, as 'secunda pars'
means literally the second part of a motet) or the quinta pars or the sexta
pars (whatever the *correct* description of your lacking part is) isn't
*really* lacking. Many prints of that era are simply incomplete.
It would be a pity for someone to travel to the library to discover the part
simply doesn't exist.
