From the copyright page:

The original work was under Crown copyright, which has now expired, and the work is now in the public domain.

The manuscript is a mixture of typed text with inserted mathematical expressions added by hand (along with other notes and corrections). This is a typeset version that attempts to capture the original manuscript.

Another recently declassified Turning paper (typeset): The Statistics of Repetition.

Important reads. Turing would appreciate the need to exclude government from our day to day lives.
