This is
not an early "AR" rear brake set up. The picture shows a separate parking brake band. The "AR"s did not have a separate parking brake band. The parking brake lever on the "AR" set the rear service brakes. This continued until June 1928 when the separate parking brake system was added.
The hub with the Shoulder as shown in the picture was used interchangeably with the more familiar Grooved hub, and there was also a third type referred to the Tapered design as shown in the September 1929 Service Bulletin. That bulletin notes that the Grooved hub will be the only type supplied in the future, so we can infer that the Shoulder, Grooved and Tapered hubs were being installed at the factory interchangeably as late as September 1929- well after the "AR" cars.
As others have mentioned, what we have here is a broken drum/hub assembly. The drum should not come off the hub. The studs are swedged or pressed/crushed into place and that locks the drum to the hub. This car should not be driven until this is repaired.
