The corresponding entry for the order with a brief specification :
'Two M40 Centrifugal Pumping Engines - 22 + 22 with Expansion Valve. Quite complete - All as per specification - Two 40" sluice valves - delivered - right and left hand'.
I am not sure if the entry is also included within the order. Perhaps 'One M5 pump side suction double standard' was a boiler feed pump or similar?
