Field windings sound like they are probably okay.

If the commutator has worn out of round, it will bounce the brushes 
out of contact and cause the commutator segments to burn where the 
brush lifts off. 

Shorts or opens in the armature windings can also cause burned 
segments. These can only be checked with a growler.

I have a growler and can also turn the commutator round again. 
Shipping an armature is a lot cheaper than shipping the whole 
generator.
