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 10 item 1, 2, and 104, and all of section 13, 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.
