Very good!
A few remarks, the link from the governor (in the camshaftcasing) is connected to a "scalearm" with a pivot seen as a screw on the servomotor pedestall, on the other side at the scalearm is a vertical thin rod operating the slide, this rod can be seen a just a little left of the servomotor (amplifier) rod going vertically down to the fuelrackleverarm. The very visible oilpipes are marked on my drawing below. There are only two pipes, supply and return. On the fwd side of the fuelracklink you have the cylinderliner lubricator driven by an arm from the fwd valverocker pushrodconnection driving the lubricator via a ratchetconnection. The pipes from lubricator are two per cylinder. The fuelracklink is connected to the fuelhandle on the maneuvring stand, I don`t think you should have any oval slots in that link as you want a precise movement and no slack. I cannot remember the excact linkage but may be you have a picture to share.
