Boiler 'Feed' pump and Connecting rod completed. What exactly it's 'feeding' to the boiler I don't know, maybe it likes Chocolate cookies !
The pump in situ, as you can see it's driven off the bottom of the Eccentric wheel, as the Eccentric rises and falls with the rotation of the Crankshaft it causes the Piston rod to slide in and out of the pump, causing it to 'pump' !
