Is the rope in pic one elastic?
On my A the rope has a steel spring cable running through the core of the rope.
The one on my town sedan is 34 inches, yours is 39 inches so it may have come from a much larger car, maybe a Caddie, or some other such vehicle.
The brackets are different from my '31 town sedan but the rope looks of the same design/maker.
Those items sure look like Model A pieces, but I am far, far from an expert, I would wait for the Guru's to chime in to be sure.
