Is this meant for the armature brushes or the brushes that ride along the collector rings?

The armature I believe. All of the brushes are the same on the Thunderbolt I have so I can't answer that. It could be both but they are curved for the armature.

Will these brushes work with a Model 2 siren?

I don't know honestly. On my model 2 they were different.

The chopper motor brushes in a Thunderbolt are the same as the collector ring brushes. A Model 2 and a Thunderbolt chopper assembly are the exact same thing, no differences motor-wise

The brushes I listed up here have springs that a tad bit big for the housing for them.

Does anyone have a spare Model a front cone, if so, please respond!!! Also if there is also a model a stator, that would also be greatly appreciated!

Hate to bump this but does anyone know where I can get brushes for a 3T22? I believe the motor is the Northwestern Electric version. The ones I have are completely worn out. Thanks!

You could try and ask CDV777-1 here on TheSirenBoard. I remember back in 2009 he received a ton of NOS Federal Signal parts including brushes for the single phase repulsion induction motors. I'm not sure if he still has any parts left but it's worth a shot.
