"While precise details are not available, it is clear that the group managed to exist in an organised form, issuing appeals, leaflets and manifestos until 1929, when it still had a clandestine press which was being produced in Moscow. (...) In exile, whether in Berlin or France, in 1930 this network was sustained by correspondence and occasional bulletins. Their work was published in England by the Workers’ Dreadnought and the Commune and in Germany by the press of the KAI/KAPD and others; but the best source of information on their activity in the early 1930s is the journal L’Ouvrier Communiste, produced by ex-Bordigists and KAPD elements with whom Miasnikov collaborated in exile in France. These documents also find a partial corroboration in the Bulletins of the Left Opposition and the writings of Trotsky where the CWG are ridiculed as marginal, sectarian ultra-leftists and called Miasnikovists."
