British report on military and diplomatic Polish codes

After checking my files for my essay on the reliability of TICOM reports i rediscovered a British report giving an overview of Polish codes. The British codebreakers obviously had some success with the codes of their close ally!

This report is important because it verifies the use of a stencil subtractor system on military attaché links, just as the Germans said.

The title is "Polish Cyphers 1942-1945", write-up by Jones-Williams (Berkeley St.) and it can be found in collection HW 47/2 of the British National Archives.

 You can download it from my Google docs or Scribd accounts.
