The interior of the R & H Green & Silley Weir heavy machine or fitters shop in the Royal Albert Dock, London. The photographer is looking down from an high vantage point showing one corner of the workshop. Two Swift machines are working on diesel engine cylinder heads and more cylinder heads are stacked on the floor, on steel stands and on a workbench. Double doors to a first aid store are on the left. The workshop has a very high roof. Transparencies numbers PCT19751 to PCT19760 were taken on the same occasion.
