Senghenydd: A History in Photographs

This is a collection of postcards depicting the aftermath of the Senghenydd disaster of October 14, 1913.  They were taken by W. Benton, a photographer from Glasgow, in the days following the explosion at the Universal Colliery which killed 439 miners.  Each postcard was hand captioned on the original negative, and numbered 1 through 25.   The ones missing from the gallery below are #'s 8,14,17 and 22.  If you know where I can locate any of the postcards in this series, or if you know anything about the photographer, please let me know.
