Victory!

I recently presented new information on the use of the M-138-A strip cipher by the State Department in the period 1940-44.  

However there was a small problem! The entries for the second half of 1944 were not in the microfilm that contains the material for 1940-44.

This meant that I had to find the microfilm with the relevant entries and this was not an easy task. After examining the finding aid for the Department of State Decimal File it was clear that the 119.25/Strip cipher entries would be in film 611.

Thankfully this turned out to be the case and I finally have all the 1944 entries. It will take me a few days to read them and then I’ll add the information in New developments in the strip cipher case.
