The final part of Peter Scott's vision for work in the Brynmawr area was what he called
The Subsistence Production Societies. The concept was that in return for voluntary work for the project, members would be able to buy goods and produce at a much lower price than they could buy in the local shops. Under an agreement made with the Government in 1936, unemployed insured workers could continue to collect "
dole" payments if they volunteered for the SPS and were available for work if any came available. Initially, Peter Scott had been asked to set up several societies, Court Perrott dairy farm at
Llandegveth was taken on and by 1937 had 100 Ayrshire cattle, pigs and sheep. It was decided to expand to form a second SPS with the purchase of two farms nearer Brynmawr and the opening of a coal level.
Jim Forrester James Grimston, the heir apparent to the title of Earl of Verulam, first came to Brynmawr with the international volunteer camp, but was later appointed to lead the SPS as Area Organiser. He continued to also work in his family business one week a month. He was known by the courtesy family title "Lord Forrester" or, more commonly, just
Jim Forrester in Wales. In 1934 he was made chairman of the SPS and in 1935 director of the Brynmawr Bootmaker factory. ==Criticisms and detractors==
