Two R. & H. Green & Silley Weir mechanical engineers at work in the engine room on board an unknown ship. One is standing on the floorplates alongside the crankcase of a diesel motor and is pulling a connecting rod out through the manhole in the side of the engine. The other man is inside the manhole holding onto the lifting rope. The location may be any of the docks in the Port of London or in Falmouth.
