1928 Model AA with 5th Wheel

This is not my post, but I found it interesting. Apparently, it has the original 5th wheel. http://maine.craigslist.org/cto/3835351752.html

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.
