So far, 4 of the anonymous manuscripts have been identified, thanks to valuable help from fellow musicians, new information in the RISM database and pure coincidence:
- XM 119 turned out to be the sinfonia to Vivaldi’s opera Teuzzone (1718).
- XM 131 has been identified as a concerto by Franz Benda (1709-1786).
- XM 136 and XM 137 are composed by Carlo Tessarini (1690-1766) and belong to his 12 Concerti à 5 con violino obligato (Paris, 1745). He composed these concertos during his time as music director at the Ospedale del Derelitti in Venice, before he moved to Urbino in 1731.
