The fireman's control station.
The green taps of the triangular shaped manifold which once controlled the stoker jet valves remain and are now used for tank heat, pipe heat etc. at the bottom of the picture. Above that the larger steel tap controls atomiser pressure within the firebox. To the right, the vertically located ratchet lever controls the flow of oil. Above that the round handle turns on the steam for the injector. The two pressure guages: the lower is steam atomiser pressure, while the upper is boiler pressure.
