Chris, the French publication Le Messerschmidt Me 323 Gigant by Jean-Lousis Roba IBSN  0-7643-1442-4 (39 Euros 
http://www.aircraft-navalship.com/pr...es-livres/1459) has a list of the Me323 by serial number, and an alphatical list of known crewmen. There is also Messerschmidt Me 321/323 by Hans Peter Dabrowski IBSN 978-2-914017-61-9(E-Bay ?) which has a constuction list and loss details of some individual aircraft. I have made a list from the GQM but it is only hand-written so if there are any specific losses you are interested in let me know,
