T.O.M. Microfilm Reel 256

(Original designation BM-42)

Table of Contents

Note from the editors - only selected documents from this microfilm reel have been completely processed and presented below in cleaned and grouped format (Section XI all translations, and Section XII Translation 385 only, identified by HTML link below). The remainder of the reel is not related to the Fischer-Tropsch process, and therefore complete processing cannot be justified at this time.

We are, however, making the entire reel contents available in raw image format, although in a small number of relatively large files (rather than a very large number of small individual images). Anyone interested in pursuing the non-FT related material on this reel may find the document in these larger raw files.
