Any Ideas?

Top one is, as it says, the ships speed in knots and distance travelled, the bottom one is an engine order telegraph, and for the Starboard engine by the labelling. The black button marked control is actually a red light. When lit it means the operator has control of the engine orders, unlit means another outstation has control.
