This is the only copy I possess. (No. 28, Jan 1955.) I don't know how long this internal discussion SPGB "newspaper" ran for.
This copy discussed relative surplus value, crises a matter concerning Paddington Branch but was mostly concerned with the so-called "Turner affair." It rumbled for a while and Turner eventually left the Party.
Details are available in the issue marking 100 years of the SPGB in 2004, in the article "Getting Splinters."
