Hopefully one of the manuals in the download is MF 01-B17-1, dated 25 August 1945 Revised 12 March 1946. This is the Index document for the rolls of microfilm that should be in the download. Originally it was T.O. 01-20E-114. There should be 26 rolls of microfilm - A-Z (omitting I and O), and AA-AM (the revisions). Attached is the first page.
