T.O.M. Microfilm Reel 233

(Original designation 37-E)

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 (items 2 through 6, 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.
