Has anyone with these engines had to replace their brushes?
Yes, unfortunately like other Ives O gauge motors of that era, they are soldiered in place onto the brush holders.
You should be able to send the whole motor out when you have the armature rebuilt and whomever does that work should be able to replace and adjust the brushes.
That being said, your brushes don't look too bad. I would probably try to use them as they are. They last a long time. Usually I find them completely worn down to the holder arms and its scraping on the commutator face because someone has over adjusted it. They need to be adjusted to apply just light pressure to the commutator.
