Possible New Research Project

Now that I know that PRAAD has nothing available after 6 March 1957, I need to formulate a new research project since obviously I can not look at the relevant Ghanaian documents dealing with the 18 December 1963 African student demonstration in Moscow. I am thinking of looking to see if there is anything in the British colonial records regarding alleged subversion by the Comintern in the 1920s and 30s. Even though the USSR really had no policy at all towards Africa until the 1950s, I am thinking that British perceptions might have been different.
