Centre milling’. Photo (6) from a series illustrating the making of a window. From page 16 of catalogue. The caption says ‘The swinging bars of horizontally and vertically centre-hung windows are formed by welding together two bars of similar section, reversed; after which the weld is cleaned off by a circular milling cutter.’ John Thurgoood, who worked there, says this picture was taken at the Witham works.
