I had posted this on OGR but haven’t gotten any response, but what was I thinking anyway, should have started it here first. I have an Ives pre-war 3253 electric engine. I have been able to rebuild the motor and re-wire, but the brush plate has, what normally is brushes, two brass arms that contact the armature. At the end of these arms, there are two small holes that I am assuming is where the brushes go, but there is nothing there. If anyone has any info on what type of brushes go there, it would be of great help.
