I'm pretty sure the upright green thing is a capacitor, although, yes, it could be a big resistor.
This is how I interpret the components.
One reason I believe that is a resistor is based on your third image in Reply #19. You can see the Ohm symbol... that was probably the last character in the resistance marking. Another is that from what I could discern from the images, its connection to the other components appeared consistent with one of the resistors in that schematic.
You're probably correct. That would match up with the diagram from the shop manual better.
I updated the labels in that image.
That hand-drawn diagram from the '74 Honda Update is probably from a preliminary drawing.
