Each of those castings is a single cylinder with 2 piston valves? There are 2 of them on the F cars and 4 on the E? Somewhere I read that 2 of the cylinders were smaller on the E.
the cylinders that you can see here are E cylinders and are a wolfe compound, that is HP and LP pistons and one valve that serves both, The E has a LH set and a RH set as laid out so the E (in this configuration) has two HPs, two larger LPs and just 2 valves . it is basically two compound engines running on one crank, the F engine is a simpler affair with only one HP and one LP and two Valves
