Looks a bit odd!

The four brushes should be equally spaced around the commutator, or
you have four missing from the bottom positions.

One set of brushes would be positive and the opposite set would be
negative, BUT it isn't as simple as that, as you have to have opposite
brushes with opposite polarities, UNLESS you have a complex wave-wound
rotor, which I doubt. It's an 8-pole machine, so I think there is more
to it than meets they eye.

The output from the brushes is fed into the field coils via the
regulating resistor or hand control. So, you have to sort out first
what other brushes should be present.

I feel that there are parts missing here, so be careful what you are
doing with it until it is established how it SHOULD be connected.
