A comprehensive edition, includes the 2nd Agnus Dei in 7 parts. I rue the day such manuscripts were converted to 'crotchet = normal unit of time' and would have preferred the minim - however, that is just me. Other conversions such as regular barring are inevitably part of our times.
The two-stave reduction is a little cramped here and there, especially as if aims to preserve the counterpoint - more space would have been nice - but this is only a guide after all.
