This steam engine indicator was made by Manchester manufacturer Isaac Storey & Sons. It would have been used to check that steam engines were working correctly. The indicator would be fitted to a steam engine and paper would be secured around the drum. The drum would rotate and the indicator would draw a graph to show whether the engine was working properly. This indicator's box contains an example of a graph on headed paper from John Musgrave and Sons of Globe Ironworks, Bolton. This suggests it may have been repaired, serviced or used there.
