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 large trolley stacked with planks is in the foreground. The motor coaster Seabreeze (1948) is passing, heading downstream, and her forepart is out of the picture. The South Eastern Gas Board works at Greenwich are in the background. Transparencies numbers P63508CT to P63514CT were taken on the same occasion.
