The engine rolls freely and runs on air. On a twice working pressure hydraulic test the boiler appeared structurally sound, with a few minor beads from stays which would take up when hot.
Most fittings leak - not unexpected on an engine that hasn't run in some years - there is wear in the motionwork and valve gear.
