In my mind it is the phenolic plate at the back end of the armature that holds the brushes against the commutator. I guess one can also call it the brush holder; Falcon 70
I just dug out the two different armatures, the left one the 11077 and the right one the earlier one. The 11077 has an oil slinger and the early one doesn’t. The other picture shows the early one in the later brush cap and you can see that the brush tubes are making contact with the armature and will short out.
