Discovered by Tom Ward (?) and published by Heinz Ristory in 1992 but without identifying the concordance. It contains a fragment of the Deo Gratias Conclamens from Munich 3223 and Cortona 2, part of a motet (or perhaps contrafactus?) and an unidentified Credo with Amen in O-dot mensuration.
The fragment is published on the Medieval Music Manuscripts from Austrian Monasteries (MMMAM) database (external link to images, above).
