Here's closeups of the brushes.

Upper pic: this brush has some tread to go with, no need to change it for trying out, although I will once I get hold of fitting brushes. the other one was worn so short that the holder rim touched the commutator, and the brush made no more contact.

Lower pic: The temporary brush, which I just twirled on to the twine, fits the holder sideways but is much flatter than original. It also has the wrong curvature, and when I get the replacement brushes, I will probably have to round out the hind edge of the new brush. Otherwise it will make excess noise and wear the commutator. The front edge will take care of itself when the brush wears down.
