Ahha, those springs are just the tensioner for the carbon brushes, they do provide some current path but most of the current actually goes through the rectangular brush holder that holds the brush in place ie spring with brush holder on left
I was thinking of the resisters that they had (usually one internally and one externally) look a bit like a piece of fencing wire in a coiled spring like this
