A general scene inside an R & H Green & Silley Weir fitters workshop in the Royal Albert Dock, London. On the right a man is operating a large red-painted machine which is being used to clean out circular grooves in a large steel component. Another man is at work on a similar machine in the left background. Four of the same type of component are on the floor near the back machine. Transparencies numbers PCT19737 to PCT19742 also show this component and machine.
