I've not seen inside the cab of one of these before, so thank you for posting this picture.
The model is based on David Lloyd George and it is interesting to see that they have even incorporated the fireman's atomisation steam manifold (the box to the left of the handbrake with two pipes running in to it) for the oil-firing system, complete with blower control levers, atomisation control valves and main shut-off valve.
The gauges are (left to right) bottom-end steam chest pressure, top-end steam chest pressure, boiler pressure, top-end fuel oil atomisation pressure, bottom-end atomisation pressure.
