Wow - what a great find. I'm never that lucky unfortunately !
Incidentally, OFFTHERAILS was quite right concerning terminology. What is missing on your 'Earl' are the COUPLING rods, which 'couple' the sets of driving wheels together. CON rods, or CONNECTING rods connect the piston rod inside the cylinder to the main driven axle. On an inside cylinder loco, such as the 'Earl', these are between the frames, and connect to huge cranks on the main driven axle itself. Whereas on outside cylinder locos, such as a 'Manor', 'Castle' or the like, the connecting rod attaches to a pin on the crank on the outside of the main driven wheels - the coupling rods then transmit the drive to the other driving wheels.
