Are all the pics on that page of the same motor? Looks like it's another one with the brushes set at an angle to the commutator, which suggests it's designed to go run mainly in one direction. Doesn't make much sense to me though, since the forklift was direct drive to the differential, wasn't it?
I think Jim likes the many-segmented comms, such as this. The only downside I can see is that it appears to have one brush per holder, rather than a pair.
