Jim,
The wing shaped spring connectors and the field coil wires attach to the second set of tubes. In the pic below you can see the ends of the brush tubes w/out brushes at 4:00 and 10:00. The wing connectors with the field wires are at about 1:00 and 7:00. You can also see how the one end of each wing shaped connector contacts the brush tubes.
There is some movement in the design, that's why I said the parts should be clean from oil and corrosion.

Here is another pic with the wing connectors and brush tubes more visible:

This motor doesn't use grease, only oil as far as I know.
