Inside the R.H. Green & Silley Weir joiners workshop at Blackwall, London. The photographer is looking towards the river Thames through the open double doors and a man is pushing a large trolley stacked with planks in the foreground. The midships of the collier James Rowan (1955) is passing, heading upstream, and the South Eastern Gas Board works at Greenwich are in the background. Transparencies numbers P63504CT to P63507CT were taken on the same occasion.
