MineArchivePowell Duffryn Steam Coal Company
One of the major South Wales coal combines of the interwar period. It acquired Merthyr Vale Colliery in the early 1930s and took over Nantgarw after 1927, operating that mine through its 1927 abandonment and 1937 reopening, and held its collieries until the nationalisation of the coal industry in 1947.
