This War Relics thread has a list of the batches of Monte Casino Cross numbers issued to units, and somebody has assisted with identification of individuals by Cross number.

Also on the forum are details of other awards and insignia such as cap eagles, it may be possible to identify your cap eagles to a particular manufacturer or theatre of production.

I would think that there will be details on the forum of the 2 Corps badges that you have (I bought one of the largest sized 2 Corps badges a few days ago (as I recall there were four sizes)).
