This is not my post, but I found it interesting. Apparently, it has the original 5th wheel.

My question is what do they use for brakes on a semi-trailer pulled by a tractor with mechinical brakes?

Looks like this one used vacuum over mechanical. See the arrow pointing to the trailer brakes.

Did the "tractor" AA use the 131" wheel base or were they a specially built unit with different drive line?

To my understanding, Ford had nothing to do with these trucks having a fifth wheel installed. That was after market like the Fruehauf ad above. As a side note, Fruehauf was making horse drawn wagons and jumped into the trailer business with the advent of motor trucks.
I have seen bump stop type brakes before, so maybe that was used. By that I mean that as brakes are applied on the tractor the forward pressure applies the trailer brakes through the fifth wheel pin mounting.

how rare are the trailers of the model A era?
