Red Mole Rising readers may be interested in some recent postings on our sister site Splits&Fusions looking at the early days of British Trotskyism:
The Communist (1932-3) – journal of the British Section of the Left Opposition ie the Balham Group
The Red Flag– agitational paper of the Communist League from 1933 – 1937
Fight- For The Fourth International-1936-1938 paper of the Marxist League of CLR James and later the Revolutionary Socialist League
And, slightly more recent(!) a large number of copies of Socialist Outlook paper associated with Gerry Healy’s Club in the late 1940s early 1950s.
