X Fliegerkorp 1942 help
 

All-

I am working on research for a book on the operations of the X Fliegerkorp from Dec 41 to Dec 42. I have/am scanning in well over 600 aerial photos/strike photos/recon map plots/annotated UK-Allied defense photos ect. from a 7 volume set of large format KTBs that have been hidden away at NARA. I also will be heading to the US Library of Congress to dig through the 336 rolls of ULTRA microfilm, which is where I need help. Does anyone know which rolls I should look towards to find the X Fl. K during that time frame? Thanks in advance for any help.
