NARA microfilm guides

[MadDog]

I am in the process of negotiating a purchase of a number of NARA microfilms. Out of this lot, there are a number of films that I dont have an index for. Can anyone tell me what the general contents are of the following microfilms are ?

T321, Roll 294
T321, Roll 431
T94, Roll 1 (I suspect this is the guide for captured Italian records)
T311, Roll 2
T311, Roll 411
T821, Roll 566
T821, Roll 21
T821, Roll 236
T821, Roll 162
T821, Roll 54
T821, Roll 139
T821, Roll 233
T821, Roll 144

thanks,
