The image is a photograph of a sign posted on a pole in a factory. The sign is white with black text and is attached to the pole with screws. The text on the sign reads "RUSTON AND HORNSBY - 8HRF 210 hp. This engine is one of a pair that was used to pump bunker oil for the ships at Fremantle Harbour, WA. It was installed at the BP terminal South Fremantle and the engine drove a large gear pump. Being bunker oil, which is thick, the oil was first heated and then pumped hot, through pipes that were in a tunnel under Fremantle City, and on to the harbour, a distance of about three miles. Electric Pumps now do the work."
